New Janus interfaces from four-dimensional N=3 gauged supergravity

We construct new supersymmetric Janus solutions from four-dimensional N = 3 gauged supergravity coupled to eight vector multiplets with SO (3) x SU (3) gauge group. This gauged supergravity admits a supersymmetric N = 3 AdS(4) vacuum with the full SO (3) x SU (3) symmetry unbroken and a family of supersymmetric N = 1, 2, 3 and non-supersymmetric AdS(4) vacua with different residual symmetries. These are expected to be dual to supersymmetric Chern-Simons-Matter (CSM) theories in three dimensions via the AdS/CFT correspondence. By considering a truncation to three complex scalar fields, we find a number of Janus solutions preserving N = 1 supersymmetry that describes conformal interfaces within N = 3 CSM theories with SO (3) x SU (3) and SU (2)(diag )x U(1) symmetries.
