Abstract

In this paper we find solutions of minimal $d=3,N=2$ gauged supergravity corresponding to Janus and RG-flow interfaces. We use holography to calculate symmetric and interface entanglement entropy as well as reflection coefficients and confirm that a recently proposed [1] inequality involving these quantities is satisfied for the solutions found here.
