Abstract: We study five-dimensional N = 4 gauged supergravity coupled to three vector multiplets with S O ( 2 ) D × S O ( 3 ) gauge group. The gauged supergravity admits two supersymmetric AdS 5 vacua. One of the vacua, at the origin of the scalar manifold R + × S O ( 5 , 3 ) / S O ( 5 ) × S O ( 3 ) , preserves N = 4 supersymmetry and the full S O ( 2 ) D × S O ( 3 ) gauge symmetry. The second AdS 5 vacuum is N = 2 supersymmetric and invariant under S O ( 2 ) diag which is a diagonal subgroup of S O ( 2 ) D and S O ( 2 ) ⊂ S O ( 3 ) . By considering a truncation to S O ( 2 ) diag invariant scalars, we find a class of Janus solutions interpolating among these vacua. These solutions should be holographically dual to conformal interfaces within the dual N = 1 and N = 2 Superconformal Field Theories (SCFTs) in four dimensions. In addition, we also find examples of solutions describing renormalization group-flow interfaces between N = 1 and N = 2 Superconformal Field Theories (SCFTs) on each side of the interfaces. All of the solutions could possibly be uplifted to eleven dimensions by a consistent truncation of M-theory on M 3 × S 2 × S 1 with a 3-manifold M 3 .
