Rényi entropy and negativity for massless Dirac fermions at conformal interfaces and junctions

Abstract We investigate the ground state of a (1+1)-dimensional conformal field theory (CFT) built with M species of massless free Dirac fermions coupled at one boundary point via a conformal junction/interface. Each CFT represents a wire of finite length L. We develop a systematic strategy to compu...
