Dear friends,

Welcome to 2023-24 FGC-Higher Structures Research Group Seminars!

This coming week, on Tuesday, September 26, 2023 at 15:00 Istanbul local 
time
(13:00 Oxford UK local time) the first speaker is Lakshya Bhardwaj from 
the Univ.
of Oxford.

The details of the seminar talk are as follows:

Speaker: Lakshya Bhardwaj (Univ. of Oxford)
Date: September 26, 2023, Tuesday.
Time: 15:00 Istanbul local time (NOTE THE TIME).
Title: TQFTs and Gapped Phases with Non-Invertible Symmetries.
Abstract:
I will discuss classification of topological quantum field theories 
(TQFTs) with
non-invertible generalized/categorical symmetries. From a condensed 
matter point of
view, this is related to the classification of gapped phases of systems 
with non-invertible
symmetries. Although the general formalism will be applicable to any
spacetime dimension, I will provide concrete details in spacetime 
dimension d=2.
As main examples, I will describe the only (1+1)d gapped phase with 
Ising symmetry
which carries 3 vacua along with relative Euler terms, and four possible 
(1+1)d
gapped phases with Rep(S_3) symmetry. Along the way, I will also discuss 
the order parameters
for such gapped phases, which carry generalized charges under 
non-invertible
symmetries.
