Holographic RG flows and $Ad{S}_5$ black strings from 5D half-maximal gauged supergravity

Abstract

We study five-dimensional $N=4$ gauged supergravity coupled to five vector multiplets with compact and non-compact gauge groups $U(1)\times SU(2)\times SU(2)$ and $U(1)\times SO(3,1)$. For $U(1)\times SU(2)\times SU(2)$ gauge group, we identify $N=4$ $Ad{S}_5$ vacua with $U(1)\times SU(2)\times SU(2)$ and $U(1)\times SU(2{)}_{\text{diag}}$ symmetries and analytically construct the corresponding holographic RG flow interpolating between these critical points. The flow describes a deformation of the dual $N=2$ SCFT driven by vacuum expaction values of dimension-two operators. In addition, we study $Ad{S}_3\times {\Sigma }_2$ geometries, for ${\Sigma }_2$ being a two-sphere $S^2$ or a two-dimensional hyperbolic space $H^2$, dual to twisted compactifications of $N=2$ SCFTs with flavor symmetry $SU(2)$. We find a number of $Ad{S}_3\times H^2$ solutions preserving eight supercharges for different twists from $U(1)\times U(1)\times U(1)$ and $U(1)\times U(1{)}_{\text{diag}}$ gauge fields. We numerically construct various RG flow solutions interpolating between $N=4$ $Ad{S}_5$ ciritcal points and these $Ad{S}_3\times H^2$ geometries in the IR. The solutions can also be interpreted as supersymmetric black strings in asymptotically $Ad{S}_5$ space. These types of holographic solutions are also studied in non-compact $U(1)\times SO(3,1)$ gauge group. In this case, only one $N=4$ $Ad{S}_5$ vacuum exists, and we give an RG flow solution from this $Ad{S}_5$ to a singular geometry in the IR corresponding to an $N=2$ non-conformal field theory. An $Ad{S}_3\times H^2$ solution together with an RG flow between this vacuum and the $N=4$ $Ad{S}_5$ are also given.
