BID - Quantum field theory with boundaries, impurities, and defects

A lattice statistical-mechanical model with exact topological defect lines exists for any fusion category, In this talk I describe how to generalise these methods to construct conserved currents in such lattice models. The currents are defined by terminating the defect lines, and are conserved when they satisfy a lattice divergence-free condition. The categorical structure allows one to find fractional-spin conserved currents in many (but not all) models, and in all known cases the corresponding lattice model is integrable. The method therefore gives a linear way of “Baxterising”, i.e. building a solution of the Yang-Baxter equation out of topological data.
