Description
Entanglement and symmetries are two fundamental concepts
in classifying quantum states. We consider a new type of
entanglement entropy which is enriched by symmetry
twisting, and show how the entropy distinguishes quantum
states, including symmetry protected and enriched
topological phases. This is based on works with Wen, Ryu,
Hung, and Caputa.
