ICMT Seminar: "Harnessing Topological Quantum Matter"

Speaker Tim Hsieh, Kavali Institute for Theoretical Physics
Date: 2/27/2017
Time: 12 p.m.
Location:

190 ESB

Sponsor:

Institute for Condensed Matter Physics

Event Type: Seminar/Symposium
 

Existing topological materials exhibit fascinating properties, but there remains significant, unharnessed potential that is essential in the quest toward quantum computing.  Topological quantum computing requires even more exotic phases of matter, which have fractionalized excitations that obey neither Bose nor Fermi statistics.  I will present a new route toward realizing such fractionalized phases of matter by literally building on existing topological phases. 

 

I will first provide an overview of new topological materials which my collaborators and I have predicted and analyzed.  These span different material classes, dimensions, and symmetries, resulting in new phenomenology and rich functionality for devices.  I will then discuss how such topological phases, when interfaced with other systems, can exhibit a “topological proximity effect” in which nontrivial topology of a different nature is induced in the neighboring system.  Finally, I will show how this enables a new entanglement-based technique (the “topological bootstrap”) for upgrading topological phases and bringing us one step closer toward a quantum computer.
