Abstract

We find a large class of new supersymmetric Janus solutions from five-dimensional N=4 gauged supergravity coupled to five vector multiplets with SO(2)_D× SO(3)× SO(3) gauge group. The gauged supergravity admits four supersymmetric AdS₅ vacua, two N=4 with SO(2)_D× SO(3)× SO(3) and SO(2)_D× SO(3)_\textrmdiag symmetric AdS₅ vacua and two N=2 with SO(2)_\textrmdiag× SO(3) and SO(2)_\textrmdiag symmetric ones. In a truncation to three vector multiplets, the gauge group is given by SO(2)× SO(3)× SO(3), and the resulting gauged supergravity admits only two N=4 supersymmetric AdS₅ vacua with SO(2)× SO(3)× SO(3) and SO(2)× SO(3)_\textrmdiag residual symmetries. By considering the SO(2)_\textrmdiag invariant sector within this truncation, we find a number of supersymetric Janus interfaces between the two N=4 vacua on both sides as well as an RG-flow interface between SO(2)× SO(3)× SO(3) and SO(2)× SO(3)_\textrmdiag symmetric vacua on each side. By repeating the analysis in the full SO(2)_D× SO(3)× SO(3) gauged supergravity, we find Janus solutions interpolating between the aforementioned four supersymmetric AdS₅ vacua as well as examples of multi-Janus interfaces between these vacua.
