Jun29 11:30am | Matthias Troyer, Microsoft (ISC2021 Keynote) Quantum Computing: From Academic Research to Real-World Applications Register and learn more here ! Read Matthias Troyer's interview with HPCwire here ! Abstract : Still in early development, quantum computing is already overturning our contemporary notions of computational methods and devices. Using new concepts of computing based in quantum physics, these computers will be able to solve certain problems that are completely intractable on any imaginable classical computer, such as accurate simulations of molecules and materials, or breaking public key encryption. While this potential is real, quantum computers are best viewed as special purpose accelerators for specific problem classes. In an effort to bring clarity to the fast-growing field of quantum computing, I will describe the hardware and software architecture of quantum computers and discuss how they differ from conventional classical high performance computers. Based on this, I will also attempt to dispel myths and hype surrounding the field and present a realistic assessment of the potential of these devices and the specific application areas on which they are expected to have a large impact. I will end by showing that quantum computing already generates value today, through quantum inspired approaches. These are quantum approaches implemented on classical HPC hardware that outperform the state of the art of classical methods known before, with applications in health care, logistics, chemistry and other areas. Bio: Matthias Troyer is a Distinguished Scientist at Microsoft and affiliate faculty at the University of Washington. He is a Fellow of the American Physical Society and Vice President of the Aspen Center for Physics. Troyer is a recipient of the Rahman Prize for Computational Physics of the American Physical Society for “pioneering numerical work in many seemingly intractable areas of quantum many body physics and for providing efficient sophisticated computer codes to the community.” He is also a recipient of the Hamburg Prize for Theoretical Physics. He received his PhD in 1994 from ETH Zurich in Switzerland and spent three years as a postdoctoral researcher at the University of Tokyo. Later, Troyer was professor of Computational Physics at ETH Zurich until joining Microsoft’s quantum computing program at the beginning of 2017. At Microsoft he works on quantum architecture and leads the development of applications for quantum computers. His broader research interests span high performance computing, and quantum computing, as well as simulations of quantum devices and island ecosystems. | Matthias Troyer |

Apr29 11:00am | Andrea Skolik, Leiden University (SciML Webinar) Reinforcement Learning With Quantum Neural Networks Zoom link : https://cmu.zoom.us/j/99244798052?pwd=dTlCYkpHK3kzdStEd3FuWWU5amJ4dz09 Website : https://www.cmu.edu/aced/sciML.html Abstract : Quantum machine learning has been identified as one of the key fields that could reap advantages from near-term quantum devices, next to optimization and quantum chemistry. Research in this area has focused primarily on variational quantum algorithms, and several proposals to enhance supervised, unsupervised and reinforcement learning algorithms with quantum computing have been put forward. Out of the three, RL is the least studied and it is still an open question whether near-term quantum algorithms can be competitive with state-of-the-art classical approaches based on neural networks even on simple benchmark tasks. In this talk, I will introduce a variational quantum algorithm for deep Q-learning and explain which architectural choices of the quantum model are crucial to make it competitive with its classical counterpart on a benchmark learning task. | Dr. Andrea Skolik Leiden University |

Apr02 11:30am | Dr. Moïra Hocevar, Institut Néel CNRS, France (CMU MSE Seminar) Growth of Nanowires Heterostructures for Quantum Devices and Nanotechnology Abstract: Nanowires are crystals with the morphology of a hair but ten thousand times smaller. They measure several microns in length and tens of nanometers in diameter. For the past twenty years, nanowires have been at the root of important breakthrough in both basic science and nanotechnology in a multitude of scientific areas. They are now commonly developed for transistor and sensor applications, light emitting diodes or solar cells. In quantum technologies, their unique properties enabled the development of bright single photon sources, spin quantum bits and nanomechanical resonators. We fabricate nanowires with crystalline semiconductor materials such as silicon which is the backbone of electronics or gallium arsenide, which emits light and is used to manufacture light emitting diodes. For a certain number of applications, it is necessary to juxtapose different semiconductors to form a heterostructure. Yet, creating heterostructures is not an easy task, especially in thin films. As different crystalline materials have different lattice parameters (distance between atoms), the lattice is strained at the junction (or interface) between two materials. This induces the formation of defects, among them dislocations which deteriorate the targeted physical properties. Thanks to their morphology, nanowires have more flexibility to release strain, preventing the formation of defects. Nanowires have the potential to host heterostructures that cannot be fabricated in standard technologies, enabling the discovery of new physical phenomena and the improvement of existing devices. During the seminar, I will present an overview of my ongoing research on nanowire heterostructures. The first part will be dedicated to embedding light emitters in silicon technology. Different semiconductor families or high-mismatch semiconductors are combined in nanowires. I will show how interfaces are built without structural defects, a prerequisite for optoelectronic devices [1]. Then, I will present superconductor-semiconductor nanowire hybrids. A particular focus will be on the development and study of Sn/InSb interfaces which have recently shown high potential for superconducting and topological quantum circuits [2]. Finally, I will present the development of an ultrasensitive tool to study the mechanical properties of nanowires using a focused electron beam [3]. [1] Beznasyuk et al (2020) [2] Pendharkar et al (2020) [3] Pairis et al (2019) Biography: Moïra Hocevar is a researcher at CNRS Néel Institute in Grenoble since January 2015. She received an Engineering degree in Materials Science from INSA de Lyon in France (2004), a master degree in Environmental Science from Université Denis Diderot in Paris (2005) and her PhD in Electronics from INSA de Lyon in 2008. Prior to joining Néel Institute in Grenoble, she was a Marie Curie postdoctoral fellow at the Technical University of Delft in the Netherlands and a Nanoscience Foundation postdoctoral fellow in Grenoble. Her research focuses on creating novel nanowire heterostructures by molecular beam epitaxy and uncovering their unique physical properties using Mhigh-end characterization tools. | Dr. Moïra Hocevar Institut Néel CNRS, France |

Mar28 4:00pm | Phase-field Modeling of Polar States in Ferroelectric Heterostructures This presentation will discuss the applications of the phase-field method to understanding and discovering new mesoscale polar states that might emerge from nanoscale ferroelectric heterostructures subject to different mechanical and electric boundary conditions. As an example, the determination of thermodynamic conditions and geometric length scales leading to the formation of ordered polar vortex lattice as well as mixed states of regular domains and vortices in ferroelectric superlattices of PbTiO 3 /SrTiO 3 using phase-field simulations and analytical theory will be presented. Switching of these vortex lattice states might produce other transient polar states such as polar skyrmions. It is shown that the stability of these vortex lattices involves an intimate competition between long-range electrostatic, long-range elastic, and short-range polarization gradient-related interactions leading to both an upper- and a lower- bound to the length scale at which these states can be observed. We further predicted the periodicity phase diagrams that show excellent agreements with experimental observations by collaborators. Location: 321 Allen Hall | Long-Qing Chen Penn State University |

Feb07 4:00pm | Interfacial Coupling and Magnetic Competition in Magnetic and Magnetoelectric Systems In the American economic system, competition is a critical driver of performance and innovation. The same can be said for materials physics. My group focuses on studying a variety of strongly correlated quantum systems, where the competition between charge, spin and orbital degrees of freedom can lead to novel or enhanced properties. It is this sensitivity that makes these materials useful for devices. A good device has a measured property (such as resistance or magnetization) that changes dramatically with an external stimulus (such as current, temperature or magnetic field). Competition is a valuable strategy for creating this interplay of parameters. Magnetic competition in magnetic systems, on the other hand, has often been seen as a hindrance. While it typically decreases the overall net magnetization, I will show that it can be utilized to generate novel phenomena useful for devices, such as giant negative magnetization and enhanced magnetization at small applied fields. While much research on magnetism utilizes large fields to strengthen the net magnetization, most devices will need to utilize small fields. While my group also collaborates on a wide range of other systems (such as topological insulators, delafossites and transition edge sensors), much of our focus has been to grow high-quality films and understand the interfacial interactions in magnetic and magnetoelectric layers. I will discuss our first observation of a magnetoelectric dead layer, which motivated our recent interest and successes in magnetic phase competition and then some of the interesting features we have discovered in complex oxide thin films.

Jan24 4:00pm | Synthesizing quantum matter with electrons and microwave photons Experimental research at the nanoscale continues to challenge our ability to predict the behavior of quantum systems. Advances with lithographically patterned solid-state electronic devices have enabled multiple platforms for the simulation of quantum matter. In particular, semiconductor quantum dots and superconducting qubits provide tools for studying the wealth of physics induced by nonlinearities at the single electron and single microwave-photon level, respectively, and have been separately pursued as enabling technologies for qubits. In recent years, hybrid devices that combine such historically distinct lines of research have received greater attention, whether to enable novel sensing or measurement applications, or to couple small systems of qubits together at long range (e.g. quantum transduction). I will showcase the rich behaviors and phases of quantum matter that coupled quantum dots can exhibit, including a surprising transport mechanism called cotunneling drag, signatures of Kondo physics with emergent symmetry , and non-Fermi liquid states. I will also discuss my work towards fabricating superconducting qubits on silicon-on-insulator substrates for hybrid device applications.

Sep26 10:00am | Statistical mechanics of the transition to turbulence How do fluids become turbulent as their flow velocity is increased? In recent years, careful experiments in pipes and Taylor-Couette systems have revealed that the lifetime of transient turbulent regions in a fluid appears to diverge with flow velocity just before the onset of turbulence, faster than any power law or exponential function. I show how this superexponential scaling of the turbulent lifetime in pipe flow is related to extreme value statistics, which I show is a manifestation of a mapping between transitional turbulence and the statistical mechanics model of directed percolation. This mapping itself arises from a further surprising and remarkable connection: laminar and turbulent regions in a fluid behave as a predator-prey ecosystem. Such ecosystems are governed by individual fluctuations in the population and being naturally quantized, are solvable by path integral techniques from field theory. I explain the evidence for this mapping, and propose how a unified picture of the transition to turbulence emerges in systems ranging from turbulent convection to magnetohydrodynamics.

Aug31 12:00pm | Theory of strong driving of silicon quantum dot qubits Quantum computation is a promising way to expand computational power as well as perform quantum simulations. There are many proposals on implementing quantum computation, including topological materials, trapped ions, superconducting circuits as well as semiconductor quantum dots. Semiconductor quantum dot qubits are promising candidates for quantum information processing and have recently made substantial experimental progress. One challenge for qubits without topological protection, however, is to suppress decoherence. Performing qubit gate operations as quickly as possible can be important to minimize the effects of decoherence. For resonant gates, this requires applying a strong ac drive. However, strong driving can present control challenges because of the strong driving effects that cannot be described using the rotating-wave approximation. Here we analyze resonant X rotations of a silicon double quantum dot hybrid qubit within a dressed-state formalism. We show that the strong driving effects can be suppressed to the point that gate fidelities above 99.99% are possible, in the absence of decoherence. When coupled to 1/f charge noise typical to our device, we further show that, by applying strong driving, gate fidelities can be above 99.9%. This shows that the quantum operations on silicon quantum dot hybrid qubits can be above the error-correction threshold, which is an important step towards realizing quantum computation.

Aug27 4:00pm | Status of the Search for Majorana Fermions in Semiconductor Nanowires Majorana fermions are non-trivial quantum excitations that have remarkable topological properties and can be used to protect quantum information against decoherence. Tunneling spectroscopy measurements on one-dimensional superconducting hybrid materials have revealed signatures of Majorana fermions which are the edge states of a bulk topological superconducting phase. We couple strong spin-orbit semiconductor InSb nanowires to conventional superconductors (NbTiN, Al) to obtain additional signatures of Majorana fermions and to explore the topological phase transition. A potent alternative explanation for many of the recent experimental Majorana reports is that a non-topological Andreev state localizes near the end of a nanowire. We compare Andreev and Majorana modes and investigate ways to clearly distinguish the two phenomena. We are also exploring how Andreev states can be chained together along the nanowire to realize the one-dimensional Kitaev model, a discrete way of generating Majorana modes.

Aug15 11:00am | Lorentzian symmetry predicts universality beyond scaling laws We present a covariant theory for the ageing characteristics of phase-ordering systems that possess dynamical symmetries beyond mere scalings. A chiral spin dynamics which conserves the spin-up (+) and spin-down (−) fractions, and , serves as the emblematic paradigm of our theory. Beyond a parabolic spatio-temporal scaling, we discover a hidden Lorentzian dynamical symmetry therein, and thereby prove that the characteristic length L of spin domains grows in time t according to , where (the invariant spin-excess ) and β is a universal constant. Furthermore, the normalised length distributions of the spin-up and the spin-down domains each provably adopt a coincident universal ( σ -independent) time-invariant form, and this supra-universal probability distribution is empirically verified to assume a form reminiscent of the Wigner surmise .

Jul31 11:00am | Using the dynamics of nanodevices for artificial intelligence Artificial neural networks are performing tasks, image recognition and natural language processing, for artificial intelligence. However, these algorithms run on traditional computers and consume orders of magnitude more energy more than the brain does at the same task. One promising path to reduce the energy consumption is to build dedicated hardware to perform artificial intelligence. Nanodevices are particularly interesting because they allow for complex functionality with low energy consumption and small size. I discuss two nanodevices. First, I focus on stochastic magnetic tunnel junctions, which can emulate the spike trains emitted by neurons with a switching rate that can be controlled by an input. junctions can be combined with CMOS circuitry to implement population coding to build low power computing systems capable of controlling output behavior. Second, I turn to different nanodevices, memristors, to implement a different type of computation occurring in nature: swarm intelligence. A broad class of algorithms inspired by the behavior of swarms have been proven successful at solving optimization problems (for example an ant colony can solve a maze). Networks of memristors can perform swarm intelligence and find the shortest paths in mazes, without any supervision or training. These results are striking illustrations of how matching the functionalities of nanodevices with relevant properties of natural systems open the way to low power hardware implementations of difficult computing problems.

Jul30 4:00pm | Theory and Modeling of Excited State and Carrier Dynamics in Organic Functional Materials We present our recent work on the computational investigations on the charge carrier transport and the excited state decay processes for organic energy materials. We developed a time-dependent vibration correlation function formalism for evaluating the molecular excited state non-radiative decay rate combining non-adiabatic coupling and spin-orbit coupling, to make quantitative prediction for light-emitting quantum efficiency. We proposed a nuclear tunneling enabled hopping model to describe the charge transport in organic semiconductors. An efficient time-dependent DMRG approach is proposed to calculate the optical spectra and carrier dynamics for molecular aggregates.

Jun01 11:00am | Temperature Memory Effect of Soft Magnetic Amorphous Ribbons The microstructure of amorphous alloys attracted many researchers for more than 40 years. Several types of local structures, such as short and/or medium rage ordering have been proposed. Recent computer simulations have made the visible spatial distribution of free volume. However, since all these heterogeneities occur on a very small scale, their effect on the material properties is usually too small to be detected experimentally. However, it can be enhanced by heat treatment under an “external field”. One typical example is the formation of a creep induced magnetic anisotropy when a ferromagnetic amorphous ribbon is annealed under tensile stress. We found by X-ray diffraction and linear thermal expansion measurements (LTE) that this induced magnetic anisotropy originates in local strains frozen-in at room temperature after the annealing stress is released. Thus, a shrinking of the ribbons is observed during post annealing due to the releasing of the frozen-in elastic strain. Figure 1 shows temperature dependence of LTE coefficient, α. All curves show a minimum around the temperature used for the first creep heat treatments. This can be explained by a spatial distribution of the viscosity, η(T). When the alloy is heated to a certain temperature, some regions are still stiff and behave like solid (small η(T)) while the adjacent regions with larger η(T) deform easily. The difference of η(T) is enhanced by the difference in local glass transition temperature. The regions with larger η(T) “glue” the elastic strain in the regions with small η(T) and, hence, freeze it in. The temperature memory effects indicate that the distribution of η(T) does not change during the first annealing. Thus η(T) of the glue regions become large again and these regions start to deform again when the original annealing temperature is reached during post-annealing. Consequently, the elastic strain in the regions with small η(T) is released. The effects of annealing time and the size of heterogeneity will be discussed in this talk.

May22 4:00pm | Moire Superlattice Bands in Dirac Materials When atomically thin two-dimensional (2D) materials are layered, they often form incommensurable noncrystalline structures that exhibit long-period moiré patterns when examined by scanning probes. In this presentation we will use graphene and hexagonal boron nitride as examples of gapless and gapped Dirac materials to illustrate how the moire superlattices due to interlayer coupling can alter the materials' intrinsic electronic properties. The derivation of the effective models for these van der Waals materials heterojunctions for arbitrary twist angles can benefit from input obtained from ab initio calculations carried out for commensurate short period crystalline structures. We will discuss how the moire pattern modified electronic structures give rise to a variety of experimentally measurable features including enhanced density of states through van Hove singularities, and flat bands, or to their suppression due to formation of band gaps.

May18 10:30am | Infrared Radiation for Healthy Living: Disease Diagnostics The incidence rates of cancers and other chronic diseases have been increasing in many regions and populations. There are more than 70,000 new cases of inflammatory bowel diseases (IBD) such as ulcerative colitis, diagnosed every year. Established diagnostic techniques for cancers and ulcerative colitis are invasive, cause discomfort, and are not cost-effective. The compliance rate for the screening of such diseases is very small due to this discomfort, expense, and the risk of complications. Thus, it is important to develop minimally invasive or noninvasive and cost-effective prescreening strategies. Attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy accompanied with different data analysis frameworks can provide an excellent spectroscopic technology to extract biochemical information from bio-fluids which can lead to the identification of diseases. Results show that dried serum samples can be used to detect the biochemical changes induced by cancers and IBDs. This potential technology can be further developed into a noninvasive, personalized diagnostic tool in which patient-to-patient differences in molecular signatures would allow the assessment of disease status and personalized drug management.

May10 4:30pm | Ultra-Fast Relaxation, Decoherence, and Localization of Photoexcited States in p-Conjugated Polymers We investigate the energetic relaxation and spatial localization of photoexcited states in conformationally disordered p-conjugated models, choosing poly(para-phenylene vinylene) as a model system. Assuming vertical excitations, the initial photoexcited eigenstates are obtained via the disordered Frenkel model. The subsequent relaxation and localization of the excited statesis determined via the disordered Frenkel-Holstein model coupled to a dissipative environment. In particular, we solve the Lindblad master equation via the time-evolving block decimation (TEBD) and quantum jump trajectory methods. The values of the model parameters physically relevant to polymer systems naturally lead to a separation of time scales, with the ultra-fast dynamics corresponding to energy transfer from the exciton to the internal phonon modes (i.e., the C-C bond oscillations), while the longer time dynamics correspond to damping of these phonon modes by the external dissipation. Associated with these time scales, we investigate the following processes that are indicative of the system relaxing onto the emissive chromophores of the polymer: 1) Exciton-polaron formation occurs on an ultra-fast time scale, with the associated exciton-phonon correlations present within half a vibrational time period of the C-C bond oscillations. 2) Exciton decoherence is driven by the decay in the vibrational overlaps associated with exciton-polaron formation, occurring on the same time scale. 3) Exciton density localization is driven by the external dissipation, arising from ‘wavefunction collapse’ occurring as a result of the system-environment interactions. Finally, we show how fluorescence anisotropy measurements can be used to investigate the exciton decoherence process during the relaxation dynamics.

May09 3:30pm | Accelerating Your Research with No-Cost Resources for Computing, AI, and Data with PSC Pittsburgh Supercomputing Center (PSC) offers powerful resources for computing, artificial intelligence, and data management and analytics that are available at no charge for open research and to support coursework. In this talk, we will survey examples of breakthroughs that are using PSC resources and ways to leverage PSC for your own research. Examples will highlight successes in genomics, AI, neuroscience, engineering, and other fields. We will highlight two PSC resources that provide unique capabilities: Bridges and Anton 2. Bridges converges high-performance computing (HPC), artificial intelligence (AI), and Big Data and offers a familiar, an exceptionally flexible user environment, applicable to whatever data analytics or simulation exceed groups’ local capabilities. Anton 2 is a special-purpose computer that dramatically increases the speed of molecular dynamics (MD) simulations to understand the motions and interactions of proteins and other biologically important molecules over much longer time periods than would otherwise be accessible. We will also describe Compass AI, a new initiative to help the community make the most of emerging hardware and software technologies for AI, develop best practices, provide education and training, and establish collaborations, especially between academia and the private sector. We outline areas of expertise at PSC where we are conducting research and open to additional collaboration. We close with a summary of opportunities to co-locate computational resources at PSC, with possible benefits of saving money, bursting to larger resources when needed, and leveraging PSC’s broad software collection.

May01 4:30pm | Two Dimensional Quantum Materials - An Atomically Thin Platform for Spintronics and Novel Spin Phenomena Two dimensional (2D) quantum materials provide a versatile experimental platform to probe spin-dependent novel quantum phenomena emerging at the nanoscale. The possibility of on-demand tuning of spin properties of 2D materials by external knobs such as electric field, substrate engineered proximity, etc., can have far-reaching implications for spintronics. I will discuss our experiments demonstrating a strong modulation of spin currents in bilayer graphene using static and fluctuating proximity exchange fields of a ferromagnetic insulator (FMI). We achieve complete spin modulation in graphene layers by controlling the direction of the exchange field of a nearby magnetic material in graphene/FMI heterostructures. A strong magnetic exchange coupling across the interface in graphene/FMI heterostructures leads to the experimental observation of full spin modulation at low externally applied magnetic fields in mesoscopic graphene spin channels. In graphene/FMI heterostructures, we also discover a novel spin dephasing mechanism due to randomly fluctuating magnetic exchange fields. This is manifested as an unusually strong temperature dependence of the non-local spin signals in graphene, which is due to spin relaxation by thermally-induced transverse fluctuations of the FMI magnetization. In the second half of my talk, I will discuss spin-charge interconversion driven by the Rashba effect in van der Waal bonded platinum/graphene (Pt/Gr) heterostructures. The interfacial spin-orbit interaction driven Rashba effect in low-dimensional systems can enable efficient and tunable spin-charge interconversion for spintronics applications. I will show that an applied electric field at the Pt/Gr Rashba interface results in a net spin accumulation in graphene, with spin polarization quantized along a direction transverse to the applied electric field. This current induced non-zero spin accumulation at the Pt/Gr interface is a direct consequence of uncompensated spin-textured Femi surfaces of the graphene Dirac states due to a symmetry-breaking electric field normal to the Pt/Gr heterostructure. Employing the Pt/Gr Rashba interface, we also realize the first experimental demonstration of the Onsager reciprocity between charge and spin via Rashba Edelstein effect (REE) and inverse-REE. This work is a significant advancement in graphene spintronics and provides an alternative experimental approach to generating and detecting spins using extrinsically tunable interfacial spin-orbit phenomena in two-dimensional materials.

Apr26 4:00pm | Open system approaches for quantum transport through tunneling junctions Quantum transport is a key area in quantum physics which presents challenges in terms of theoretical description. In this talk, I will present how the non-equilibrium dynamics of tunneling junctions weakly coupled to baths of fermionic or bosonic particles can be investigated using open system approaches, namely input-output formalisms and master equations. As a specific example, I will first present our study of electron transport in a quantum dot tunneling junction connecting two normal or superconducting leads, where both single-particle and Cooper-pair tunneling are considered. In particular, I will show how signatures of Andreev bound states can be obtained in the output currents. Then, I will present our results on spin transport in a quadratic spin system connecting baths modeled as XXZ spin chains. Based on non-Markovian master equations for the system and t-Matrix Product States simulations to compute the bath correlation functions, we showed that the spin current through the system can be enhanced due to the presence of the interaction in the baths as well as exhibit transient rectification (i.e. different current under bias exchange). Finally, I will sketch a more general outlook on how non-Markovian master equations could be used to study the transport properties of a system of unknown spectrum, which is particularly useful for the case of complicated time-dependent or many-body system Hamiltonians.

Apr23 4:30pm | Beyond Classical Thermodynamics This colloquium aims to explain why classical thermodynamics is insufficient for solids. After a review of classical equilibrium and non-equilibrium thermodynamics, two examples will be considered, grain growth and crystal plasticity, the latter one in more details. The major complication for development of thermodynamic theory for these cases was the lack of understanding of phase flow geometry. Recently, this geometry was described for dynamics of edge dislocations. Based on this finding, thermodynamics of crystal plasticity can be constructed. It includes two new thermodynamic parameters, entropy and temperature of microstructure.They have simple physical meaning: the rate of microstructure entropy coincides with the rate of slip avalanches while microstructure temperature is average energy drop in a slip avalanche. Perhaps, the phase flow geometry and the corresponding thermodynamic are common for many avalanche-type phenomena. Location: Thaw Hall 102 | Victor Berdichevsky Wayne State University |

Apr13 1:00pm | Large-Scale Forces and Small-Scale Experiments: Levitated Optomechanics for Precision Gravitational Measurements We set out to combine a mechanical system in which classical mechanics breaks down and quantum mechanics must be used with a seemingly unlikely application, measurement of the strength and effects of gravity. Our optomechanical system consists of a silica microsphere levitated in ultra-high vacuum in a magneto-gravitational trap. The microsphere is trapped in a magnetic field gradient created by permanent magnets and ferromagnetic pole pieces using the weak diamagnetism of the particle. With optical position measurements and feedback, the mechanical motion can be cooled by several orders of magnitude, ideally reaching the quantum ground state. The extreme sensitivity of this optomechanical system to external forces makes it a promising approach to a new measurement of the Newtonian gravitational constant. Furthermore, by measuring the decoherence rate of non-classical motional states of the trapped particle, it may be possible to place limits on theories of gravitational decoherence.

Mar29 4:00pm | Andreev and Majorana Weyl crossings in multi-terminal Josephson junctions We analyze the Andreev spectrum in a four-terminal Josephson junction between topological superconductors. We find that a topologically protected crossing in the space of three superconducting phase differences can occur between the two Andreev bound states with lower energy. We discuss the possible detection of this crossing through the transconductance quantization, in units of 2e^2/h, between two voltage-biased terminals. Our prediction provides another example of topology in multi-terminal Josephson junctions. Location: 321 Allen Hall | Manuel Houzet CEA - Grenoble Alpes University |

Mar16 9:30am | In Pursuit of an Immortal Cathode: Electrical Energy Storage using MnO2 Nanowires that Never Die Rechargeable lithium ion (Li + ) batteries lose their ability to store charge over time. Whether they power your phone, your laptop, or your automobile, after 500-1000 recharge cycles they lose 20-40% of their capacity and must be replaced. Sony introduced the first commercial Li + battery in 1990, but 27 years later our understanding of WHY they fail is still in its infancy. Li + batteries have four parts: An anode (usually graphite), a cathode (usually a metal oxide), a separator membrane that is located between them, and a salt solution containing Li + . In our research, we have focused attention on one cathode material called ∂-MnO 2 . Our goals have been to increase the amount of energy we can store, to increase the rate at which we can deliver this energy, and to extend the lifetime of the cathode. Now, you might think that the worst way to make a battery cathode last longer would be to make it smaller! But we have discovered a process for preparing ∂-MnO 2 nanowires - just 60 – 600 nm in diameter and up to a centimeter in length – that never fail, and rarely lose any energy storage capacity, across 100,000 charge/recharge cycles. In this talk, I’ll discuss these unusual nanomaterials and what they may mean for the future of electrical energy storage. | Reginald Penner University of California, Irvine |
Mar15 4:00pm | The Science for Failed Public Policy: Why Congress Doesn’t Fund Research Introduction: In the halls of Congress there is widespread agreement about the role of R&D in the success of the America’s most innovative corporations. However, too often lawmakers view government models of discovery, from NASA to public university research labs, as obsolete and costly superstructures in today’s .com marketplace. What happened to the case for public exploration and discovery and why shouldn’t the private sector be trusted to find the cure for Grandma’s dementia or Johnny’s brain tumor? Long-time Washington political insider, former lobbyist, Administration appointee, and AIMBE’s Executive Director, Milan Yager, will reveal the hidden truth about why Congress doesn’t fund needed biomedical research. Results and Discussion : This presentation will highlight innovations and achievements made possible from past federal investments in basic research; such as the internet, wireless communications, even mapping the human genome. Today, Congress seems less interested in past accomplishments as they assume new priorities to balance the budget, reduce government, and free the private sector to assume long-standing government responsibilities for innovation and discovery. How did Congress make spending decisions to permit federal R&D spending to be flat for over a decade? Learn about why Congress is no long accountable for reduce investments in basic research. Discover three secrets to making a winning case for federal funding for medical and biological research. Learn practical steps to successfully getting your point across to a Member of Congress. Find out how to brand your research as the Sputnik in the race to cure cancer, manage chronic disease, or Type I diabetes. Conclusions: Arming yourself with the strategies for the political warfare in the case for innovation is more than just changing public policy; it can provide the key to changing the future landscape of new biomedical materials, products or procedures. Attendees will get insight into America’s next biomedical “moonshot” initiative. Location: 157 Benedum | Milan Yager Executive Director, American Institute for Medical and Biological Engineering |
Mar13 12:00pm | Mermin in Bananaworld: Bub on Quantum Mechanics In the 1980s, David Mermin derived a simple example of a Bell inequality and showed that it is violated in measurements on entangled quantum systems. In this talk, I reanalyze Mermin’s example, using correlation arrays, the workhorse in Jeffrey Bub’s Bananaworld (2016). For the class of all non-signaling correlations conceivable in the kind of experiment considered by Mermin, I derive both the Bell inequality, a necessary condition for such correlations to be allowed classically, and the Tsirelson bound, a necessary condition for them to be allowed quantum-mechanically. I show that the Tsirelson bound for these experiments follows directly from the geometry going into their quantum-mechanical analysis. I use this example to promote Bubism (not to be confused with QBism though both are information-theoretic approaches to the foundations of quantum mechanics). I do so by comparing the rules for probabilities in quantum mechanics, illustrated by my Bubist reanalysis of Mermin’s example, to the rules for spatio-temporal behavior in special relativity.

Mar12 4:30pm | How will online learning change the future of STEM courses? The concept of “courses ” has not changed much over centuries. However, online learning technology is quickly starting to challenge our understanding of what it means by a “course”. The abundance of online learning resources challenges the role of courses being the disseminators of knowledge, while the high registration numbers and low finishing numbers of Massive Open Online Courses (MOOCs) challenges not only the necessity to “pass” a course, but also the optimum length and scope of a course. Given the fact that more than 70% of today’s undergraduate students are non-traditional in one way or another, it might be a good time to think about how online learning technology might help to evolve the structure of courses to accommodate an increasingly diverse student population. In this workshop, I will initiate the discussion of “what might a future STEM course look like”, by introducing three relatively old ideas: mastery-based learning, flipped or blended classroom , and modularized instructional design. I will talk about how those ideas, when combined with the latest online learning technologies, might re-shape how students take a course, how teachers teach a course, and how instructors create a course , especially for STEM disciplines. We will also brainstorm about what STEM instructors can do to embrace the possible changes ahead. Location: Thaw Hall 102 | Zhongzhou Chen University of Central Florida |

Dec08 11:30am | Structure-Property Relationships in Nanostructured Materials: Aqueous Semiconductor Interfaces Understanding structure-property relationships in fields as diverse as nanoscale electronic junctions, heterogeneous catalysis, electrochemistry and energy storage often starts by meeting the challenge of identifying key structure motifs. For the theorist this is followed by tackling the problem of calculating the relevant functional characteristics, also challenging, particularly for excited state properties. I will discuss the modern toolbox for these problems, including a brief outline of the basic physical ingredients of modern manybody perturbation theory which enables studies of excited state properties. I will then discuss its application in the context of the search to develop new materials for use in photocatalysis. In particular, I will discuss the search for key structural motifs at semiconductor-water interfaces and the connection to electrochemical energy level alignment.
