Speaker biography: Laura Ruetsche's research focuses on the foundations of physical theories, particularly quantum theories. Her book Interpreting Quantum Theories (Oxford), published in May 2011, was a co-winner of the 2013 Lakatos Award in philosophy of science. The book aims to use peculiar features of quantum field theories to challenge entrenched accounts of what a quantum theory is and how a physical theory comes to be associated with a collection of worlds that are by its lights possible.

Artificial Atoms: Quantum Optics and Spin Physics of Quantum Dots

Semiconductor quantum dots (QDs) are nanoscopic crystals that are often called artificial atoms. Charge carriers trapped within them have discrete energy levels in the fashion of single atoms, and they absorb and emit light at discrete wavelengths corresponding to those energy levels. Because of this, in many ways QDs behave like the canonical two-level quantum system, which makes them suitable for experiments involving the quantum nature of light, which is called quantum optics. For this reason and for their potential uses in quantum information applications, QDs attract great scientific...

Accelerating the Computational Discovery Of Catalyst Design Rules and Exceptions with Machine Learning

Over the past decade, first-principles computation has emerged as a powerful complement to experiment in the discovery of new catalysts and materials. In many cases, computation has excelled most in distilling rules for catalyst structure-property relationships in well defined spaces such as bulk metals into descriptors or linear free energy relationships. More development is needed of computational tools for them to show the same promise in emerging catalytic materials such as single-site metal-organic framework catalysts or single atom catalysts that have increased promise of atom...

Qing Li, assistant professor of electrical and computer engineering at Carnegie Mellon University, is the recipient of a prestigious 2019 Young Faculty Award from the US Defense Advance Research Projects Agency (DARPA). He received the award based on his research proposal titled "Visible and mid-infrared frequency comb generation in wide-bandgap photonic materials."

Band Engineering for Quantum Simulation in Circuit QED

The field of circuit QED has emerged as a rich platform for both quantum computation and quantum simulation. Lattices of coplanar waveguide (CPW) resonators realize artificial photonic materials in the tight-binding limit. Combined with strong qubit-photon interactions, these systems can be used to study dynamical phase transitions, many-body phenomena, and spin models in driven-dissipative systems. I will show that these waveguide cavities are uniquely deformable and can produce lattices and networks which cannot readily be obtained in other systems, including periodic lattices in a...

Anomalous Velocity and Geometry in Wave Mechanics

In electronic band theory the dynamics of electrons in crystal lattices can exhibit novel phenomena associated with the anomalous velocity. Modern work on this subject revives an idea which appeared in its primitive form some fifty years ago to interpret the anomalous Hall effect in magnetically ordered states of matter, namely the appearance of a Hall conductivity in materials that have spontaneously broken time reversal symmetry without an applied magnetic field. The signature of the anomalous velocity is the coupling of electron motion to applied static and time-dependent fields through...

SEISMIC: The Sloan Equity and Inclusion in STEM Introductory Courses Project

Monday, September 23, 2019 - 4:00pm

Equity and inclusion are important goals for higher education. Data can play a central role in achieving these goals. First, data are essential for probing equity. To provide an example, I will describe the discovery of a pattern of gendered performance differences in large foundational courses, both at Michigan and at an array of other Universities. Data can also help create solutions, as when we test new course designs and develop tools that personalize education. 
Over the last year, a group of ten large public research universities have launched the Sloan Equity and Inclusion in...
