SUMMARY:On Symmetries\, Boundaries\, and Entanglement Entropy - Brandon Ra
 yhaun\, Stony Brook University

CONTACT:Laurens Lootens
DESCRIPTION:In this talk\, I will discuss a class of "generalized tube alg
 ebras" which encode how topological line defects  of 1+1d QFTs interact wi
 th junction operators\, i.e. operators which sit at the intersection point
  of a collection of boundaries and interfaces. I will then describe how va
 rious aspects of the representation theory of these symmetry algebras can 
 be studied using three-dimensional topological field theory techniques. Wi
 th this machinery in hand\, I will explain two different ways in which one
  can refine partition functions\, focusing on the case of the annulus\, so
  that they carry information about the action of a finite symmetry. The pr
 esentation will be organized around the derivation of a symmetry-resolved 
 version of the Affleck-Ludwig-Cardy formula which\, among other things\, h
 as applications to entanglement entropy.
