1. Classical Computing with Topological States: Coping with a post-Moore World

   21 Jun 2021 | | Contributor(s):: Avik Ghosh

   There are two examples I will focus on ? one is doing conventional Boolean logic at low power below the thermal Boltzmann limit, using the topological properties of Dirac fermions to control transmission across a gated interface. The other is doing collective computing using temporal state...

3. Fundamental Properties of a New van der Waals Material: Tellurium

   01 Apr 2021 | | Contributor(s):: Peide "Peter" Ye

   We report the first experimental observation of Weyl fermions in a semiconductor -- high-quality n-type tellurene (the two-dimensional form of tellurium) achieved by atomic layer deposited dielectric doping.

4. Tunneling Into Emergent Topological Matter

   14 Jan 2021 | | Contributor(s):: Jia-Xin Yin

   n this talk, I will discuss the proof-of-principle methodology applied to study the quantum topology in this discipline, with particular attention to studies performed under a tunable vector magnetic field, which is a relatively new direction of recent focus...

6. Josephson Detection of Multiband Effects in Superconductors

   07 Sep 2020 | | Contributor(s):: James Williams

   In this talk focus be given to the modification of conventional Josephson effects due to the loss of time reversal symmetry found to exist in proximity-induced Josephson junction of SnTe nanowires.

8. Engineering Rashba Spin-Orbit Coupling for a Bose-Einstien Condensate

   28 Aug 2020 | | Contributor(s):: Ian B. Spielman

   I will describe our engineered Rashba spin-orbit coupling for a cold atomic gas giving non-trivial topology, without the underlying crystalline structure that conventionally yields integer Chern numbers.

9. Metaphotonics and Metasurfaces Governed by Mie Resonances

   14 Jul 2020 | | Contributor(s):: Yuri Kivshar

   This talk will highlight some recent advances in all-dielectric Mie-resonant metaphotonics including active and nonlinear nanophotonics as well as the recently emerged fields of topological photonics.

10. Electronic States of Novel Topological Materials Studied by ARPES

    14 Jul 2020 | | Contributor(s):: Takafumi Sato

    In this talk, we will present novel electronic states of some exotic topological materials such as TSMs and topological superconductors, studied by angle-resolved photoemission spectroscopy (ARPES). We will focus on the following subjects.

11. Topological Materials as Platforms for New Particles and Electromagnetic Responses

    06 Jun 2019 | | Contributor(s):: Joel Moore

    We then turn to how topological Weyl and Dirac semimetals can show unique electromagnetic responses; we argue that in linear response the main observable effect solves an old problem via the orbital moment of Bloch electrons, and how in nonlinear optics there should be a new quantized effect,...
