Spectral gaps without frustration

Speaker: Marius Lemm
6:00pm | Dilworth Room
In spin systems, the existence of a spectral gap has far-reaching consequences. "Frustration-free" spin systems form a subclass that is special enough to make the spectral gap problem amenable and, at the same time, broad enough to be physically relevant. We discuss "finite-...
