Description

We investigate non-local charges for perturbations of two-dimensional conformal field theories that arise as perturbations of conformal defects. We find solutions for a wide range of perturbations including the well-known (1,2), (1,3) and (1,5) integrable perturbations of Virasoro minimal models (with associated local conserved charges), but we also find solutions for other bulk perturbations, such as (1,7), and we contrast this with the (non) existence of local conserved charges.
