Intertwining Defects and Fermion-Boundary Scattering from TQFT
We construct conformal boundary conditions of free Dirac fermions that preserve chiral, anomaly-free symmetries, and determine the associated fermion-boundary scattering, using the TQFT/CFT framework. We apply the construction to several previously unresolved examples: higher-charge monopoles in non-chiral QED, a famil...
