    A bstract In this paper, we continue the study of Janus and RG-flow interfaces in three dimensional supergravity continuing the work presented in [1]. We consider $$ \mathcal{N} $$ N = 8 gauged supergravity theories which have a $$ \mathcal{N} $$ N = (4 , 4) AdS 3 vacuum with D 1 (2 , 1; α ) × D 1 (2 , 1; α ) symmetry for general α . We derive the BPS flow equations and find numerical solutions. Some holographic quantities such as the entanglement entropy are calculated.

  2. ; ; ( , Journal of High Energy Physics)
    A bstract In this paper, we construct Janus-type solutions of three-dimensional gauged supergravity with sixteen supersymmetries. We find solutions which correspond to interfaces between the same CFT on both sides, as well as RG-flow interfaces between CFTs with different numbers of supersymmetries and central charges. The solutions are obtained by solving the flow equations derived from the supersymmetry variations, and they preserve some fraction of the supersymmetries of the AdS 3 vacua.
