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 $SO(3)\times SU(3)$ gauge group. This gauged supergravity admits a supersymmetric $N=3$ $Ad{S}_4$ vacuum with the full $SO(3)\times SU(3)$ symmetry unbroken and a family of supersymmetric $N=1,2,3$ and non-supersymmetric $Ad{S}_4$ 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 $SO(3)\times SU(3)$ and $SU(2{)}_{\text{diag}}\times U(1)$ symmetries.
