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

Abstract

Abstract We construct new supersymmetric Janus solutions from four-dimensional $$N=3$$ N = 3 gauged supergravity coupled to eight vector multiplets with $$SO(3)\times SU(3)$$ S O ( 3 ) × S U ( 3 ) gauge group. This gauged supergravity admits a supersymmetric $$N=3$$ N = 3 $$AdS_4$$ A d S 4 vacuum with the full $$SO(3)\times SU(3)$$ S O ( 3 ) × S U ( 3 ) symmetry unbroken and a family of supersymmetric $$N=1,2,3$$ N = 1 , 2 , 3 and non-supersymmetric $$AdS_4$$ A d 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 $$N=1$$ N = 1 supersymmetry that describes conformal interfaces within $$N=3$$ N = 3 CSM theories with $$SO(3)\times SU(3)$$ S O ( 3 ) × S U ( 3 ) and $$SU(2)_{\text {diag}}\times U(1)$$ S U ( 2 ) diag × U ( 1 ) symmetries.
