Tomorrow our new postdoc Ramona Wolf will tell us about her research, in particular "Fusion categories and lattice models". See below for the abstract. We start at 2pm on Zoom: https://ethz.zoom.us/j/362994444

Best,

Abstract:

While fusion categories are already an interesting subject from a purely mathematical perspective, they can furthermore be used in physics to study conformal field theories via 1D and 2D lattice models. In my talk I will explain the basic theory of fusion categories and explain their connection to conformal field theory. I will also discuss how to construct a lattice model from a fusion category (and the context in which this problem arises) via the Levin-Wen stringnet model.
