“Symmetry and topology in quantum materials – from Weyl semimetals to correlated topological insulators” by Andrew Potter (UC Berkeley)

Series: 
Condensed Matter Journal Club Seminars

Motivated by recent developments in correlated and strongly spin-orbit coupled materials, I will explore new directions for symmetry protected topological phases of matter beyond the paradigm of topological band insulators. As a first example, I will discuss Weyl semimetals – 3D analogs of graphene with topological features, focusing on possible material realizations and unconventional experimental signatures.  Next, I will show that strong electron interactions enable many new topological-insulating phases not captured by band-theory, and explain some recent theoretical advances in understanding these correlated topological insulator phases.
