A Toy Model for Topological Entanglement Features in 1+1D Integrable Quantum Field Theory

In this paper we investigate an entanglement measure, the R\'enyi entropy, in a 1+1D integrable quantum field theory known as the Federbush model. This is a deformation of the theory of two massive Dirac fermions by means of a bilinear term in the $U(1)$ currents that couples the two fermion species. This deformation g...
