Title:Entanglement Entropy in Chern-Simons Quantum Field Theories
Abstract:
The fractional quantum Hall effect provides an example of a topological
phase of matter. Such phases are of physical interest due to their
great stability and exotic excitations. Because these phases are not
governed by any local order parameter, one needs new numbers
characterize their topological phase. One such number is their quantum
entanglement entropy.
I will begin with a brief introduction to Chern-Simons theory, a low
energy effective description of many topological phases. After
introducing the concept of entanglement entropy, I will conclude with
its computation for Chern-Simons theory.
