Speaker: Brent Perreault, University of Minnesota
Subject: Semimetal Physics in Kitaev Spin Liquids

Semimetals and Spin Liquids are two sought-after states in modern condensed matter physics. In this talk I will discuss the Kitaev spin liquid and its excitations. I will then present Raman scattering as a probe for these exotic states in candidate spin-orbit coupled materials. It turns out that Raman scattering probes a fermionic quasiparticle in this system that realizes effective semimetal physics. Finally, I will speculate about Raman signatures of semimetal surface modes.
