Abstract
Topological defect lines in 2D CFTs have experienced a resurgence in the context of categorical symmetries. In this talk, I will present the lattice realization of these lines for unitary Minimal Models. I will use spin chains, such as the Transverse Field Ising model and the Three-State Potts model, as well as integrable Restricted Solid-on-Solid (RSOS) models, for these constructions. I will compare known defect line operators in spin chains, RSOS models, and anyonic chains and discuss the lattice realization of a defect line which was previously unknown. I will also use these 1+1D models to discuss boundary RG flows between defect CFTs.
