Janus and RG interfaces in three-dimensional gauged supergravity II: General $\alpha$

Abstract

In this paper, we continue the study of Janus and RG-flow interfaces in three dimensional supergravity continuing the work presented in [1]. We consider $\mathcal{N}=8$ gauged supergravity theories which have a $\mathcal{N}=(4,4)$ $Ad{S}_3$ vacuum with $D^1(2,1;\alpha )\times D^1(2,1;\alpha )$ symmetry for general $\alpha$. We derive the BPS flow equations and find numerical solutions. Some holographic quantities such as the entanglement entropy are calculated.
