Effective field theories for interacting boundaries of 3D topological crystalline insulators through bosonisation
Abstract Here, we analyse two Dirac fermion species in two spatial dimensions in the presence of general quartic contact interactions. By employing functional bosonisation techniques, we demonstrate that depending on the couplings of the fermion interactions the system can be effectively described b...
