Title: Classification of Super-modular Categories
Abstract: I will explain the connection between topological quantum computing and tensor
categories. The most promising proposal for topological quantum computation is
anyon braiding in 2D topological phases of matter. The algebraic theory of 2D
topological phases corresponds to tensor category theory in a very precise way.
I will focus on super-modular categories, a type of tensor category related to
fermionic topological phases similarly to the way that modular categories are
related to bosonic phases.
Super-modular categories are interesting from a purely mathematical standpoint
as well. For example, any unitary pre-modular category is the
equivariantization of a modular or super-modular category. In this talk, I will
discuss a number of properties of super-modular categories parallel to those of
modular categories. Time permitting, I will also discuss the classification of
super-modular categories of rank 8.
