Janus solutions in three-dimensional N=8 gauged supergravity

Abstract

Janus solutions are constructed in $d=3$, $\mathcal{N}=8$ gauged supergravity. We find explicit half-BPS solutions where two scalars in the $SO(8,1)/SO(8)$ coset have a nontrivial profile. These solutions correspond on the CFT side to an interface with a position-dependent expectation value for a relevant operator and a source which jumps across the interface for a marginal operator.
