Two and three-dimensional (2D/3D) hybrid materials

  • 19 January 2018

In the recently published paper in Journal of Nanoscale, Randall M. Feenstra and their colleagues have demonstrated the importance of 2D layer thickness and transition metal dichalcogenide (TMD) in the transport properties of the hybrid structure, where monolayer TMDs exhibit direct tunneling through the layer, while transport in few layer TMDs on GaN is dominated by p–n diode behavior and varies with the 2D/3D hybrid structure. They have shown the scalable synthesis of molybdenum disulfide (MoS2) and tungsten diselenide (WSe2) via metal organic chemical vapor deposition (MOCVD) on gallium nitride (GaN), and elucidated the structure, chemistry, and vertical transport properties of the 2D/3D hybrid.

Direct conversion of unsubstituted furan into benzene

In the recently published paper in Journal of ACS Catalysis, Giannis Mpourmpakis and their colleagues have discussed the direct Catalytic Conversion of Biomass Derived Furan and Ethanol to Ethylbenzene. They have reported a synthetic strategy to convert biomass-derived unsubstituted furan to aromatics at high selectivity, especially to ethylbenzene via alkylation/Diels-Alder cycloaddition using ethanol, while greatly reducing the formation of the main side product, benzofuran, over zeolite catalysts.

Four-dimensional physics in two dimensions

  • 5 January 2018

Kevin Chen and team have demonstrated that the behavior of particles of light can be made to match predictions about the four-dimensional version of the "quantum Hall effect"—a phenomenon that has been at the root of three Nobel Prizes in physics—in a two-dimensional array of "waveguides."

“For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials that were theorized to exist only in four-dimensional space"

Understanding of the superior stability of Silicon- and oxygen-containing hydrogenated amorphous carbon in harsh environments

  • By Leena Aggarwal
  • 3 January 2018

Recently, Tevis D. B. Jacobs and colleagues have shown how silicon- and oxygen-containing hydrogenated amorphous carbon (a-C:H:Si:O) coating enhance the thermal stability in vacuum, but tremendously increases the thermo-oxidative stability and the resistance to degradation upon exposure to the harsh conditions of low Earth orbit (LEO). These findings provide a novel physically-based understanding of the superior stability of a-C:H:Si:O in harsh environments compared to a-C:H.

International Conference on Quantum Communication, Measurement and Computing (QCMC)

  • By Leena Aggarwal
  • 8 January 2018

The International Conference on Quantum Communication, Measurement and Computing (QCMC) was established in 1990 to encourage and bring together scientists and engineers working in the interdisciplinary field of quantum information science and technology.

To date, thirteen such meetings have been held and the fourteenth is being organized by Quantum Science and Technologies Group (QST)Louisiana State University on March 12-16, 2018. QST group conducts research on atomic, molecular, and optical physics, the foundations of quantum mechanics, photonic band gap and meta materials, quantum information theory, quantum complexity theory, quantum error correction, quantum optics, optical quantum computing, quantum sensors, quantum imaging, and relativistic quantum information theory. It collaborates with a number of university and industrial research groups around the world, and we receive financial support for our research from a number of sources.

Southwest Quantum Information and Technology

  • 8 January 2018

SQuInT is a consortium of universities, national labs, and industrial labs, with concentration in the southwestern United States. The SQuInT meeting has a strong tradition of mixing invited talks from world-class leading researchers with talks by junior researchers across the SQuInT network, to promote an interactive environment. The meeting brings together the broad community of researchers in Quantum Information Science, including experimental physicists, theorists, and computer scientists.

The 20th Annual SQuInT Workshop is being organized by the Center for Quantum Information and Control (CQuIC). The CQuIC is a research center co-located at the University of New Mexico in Albuquerque and the University of Arizona in Tucson. Research at CQuIC is focused on on quantum information and computation, quantum control and measurement, quantum metrology, and quantum optics and communication, and they have extensive theoretical and experimental research programs in all these areas

    Workshop on 2D Quantum Metamaterials

    • By Leena Aggarwal
    • 8 January 2018

    The workshop on 2D Quantum Metamaterials is dedicated to the commonalities between fabrication, theoretical prediction, and alternative approaches to tunable quantum materials, including cold-atom realizations. Theoretical efforts served by this new simulation platform include Hubbard model systems, design of 2D materials, and other exotic materials.

    The workshop will be organized around:

    1. all-invited talks by leading researchers

    2. breakout sessions for discussions and future plan

    3. published Workshop Summary Report

     

    Quantum Leaps

    • By Leena Aggarwal
    • 8 January 2018

    Quantum is an open-access peer-reviewed journal for quantum science and related fields. Quantum is launching a pilot outreach project, Quantum Leaps, where scientists write a rigorous and accessible popular science version of a research paper, which are then reviewed by school students, under the supervision of a researcher. The goals of this project are three-fold:

    1. Teach the process of peer review to school students by direct experience;

    2. Get students interested in the science of quantum computing and information; and

    3. Provide a venue for researchers to showcase effective science communication in quantum sciences.

    After peer review, the best articles will be published in Quantum Views, and the reviewers will be invited to give a talk about the experience. This project is inspired by Frontiers for Young Minds, which implements the same idea in fields such as biology, psychology and space science. Quantum Leaps is coordinated by Chris Ferrie and Lídia del Rio.

    Quantum Decision Theory Workshop 2018

    • By Leena Aggarwal
    • 20 December 2017

    The goal of this two-day workshop is to bring together decision/game theorists and physicists to find a common language in discussing uncertainty. It is organized by the Game Theory Group of the University of Pécs. There will be dominantly invited talks by quantum information scientists and game theorists. Contributed posters are welcome.​
