Janus and RG-flow interfaces from matter-coupled F(4) gauged supergravity

Abstract

We study supersymmetric Janus solutions from matter-coupled $F(4)$ gauged supergravity coupled to three vector multiplets and $SO(4)\sim SO(3)\times SO(3)$ gauge group. There are two supersymmetric $Ad{S}_6$ vacua preserving all supersymmetries with $SO(3)\times SO(3)$ and $SO(3{)}_{\text{diag}}$ symmetries dual to $N=2$ SCFTs in five dimensions. We consider a truncation to $SO(2{)}_{\text{diag}}\subset SO(3{)}_{\text{diag}}$ singlet scalars and find a number of new supersymmetric Janus solutions preserving eight supercharges. These solutions holographically describe conformal interfaces within $N=2$ five-dimensional SCFTs involving deformations by source terms and vacuum expectation values of relevant and irrelevant operators. Apart from the Janus solutions interpolating between $SO(3)\times SO(3)$ $Ad{S}_6$ vacua, some of the solutions have $SO(3{)}_{\text{diag}}$ $Ad{S}_6$ vacua generated by holographic RG flows from the $SO(3)\times SO(3)$ phases on both sides. We also give an evidence for solutions describing RG-flow interfaces with $SO(3)\times SO(3)$ $Ad{S}_6$ vacuum on one side and $SO(3{)}_{\text{diag}}$ $Ad{S}_6$ vacuum on the other side. The solutions provide first examples of Janus solutions involving more than one $Ad{S}_6$ vacuum in six-dimensional gauged supergravity.
