D4-branes wrapped on topological disks from matter-coupled F(4) gauged supergravity
Abstract
We study a number of supersymmetric AdS4× Σ solutions with Σ being a topological disk with non-trivial U(1) holonomy on the boundary or a ``half-spindle'' from matter-coupled F(4) gauged supergravity. The gauged supergravity is coupled to three vector multiplets with SO(3)× SO(3) gauge group. The resulting solutions preserve eight supercharges and SO(2)× SO(2) or SO(2)diag symmetries and are expected to be dual to N=2 SCFTs in three dimensions arising from compactifications of five-dimensional N=2 SCFT on a half-spindle. All of the solutions lie within the U(1)× U(1) subsector of the matter-coupled F(4) gauged supergravity that can be embedded in massive type IIA theory. After uplifted to ten dimensions, the solutions can be interpreted as a system of D4-D8-branes wrapped on Σ. Some of the solutions are asymptotic to a locally AdS6 geometry and can be identified as codimension-2 conformal defects within the N=2 SCFT in five dimensions. For these solutions, the circle inside Σ decompactifies in the AdS6 limit rendering the holographic free energy infinite. There also exist solutions with finite free energy in the dual three-dimensional SCFTs. In addition, we show that the results both extend the previously known solutions and provide a novel class of solutions.

AB - We study a number of supersymmetric AdS_4× Σ solutions with Σ being a topological disk with non-trivial U(1) holonomy on the boundary or a ``half-spindle'' from matter-coupled F(4) gauged supergravity. The gauged supergravity is coupled to three vector multiplets with SO(3)× SO(3) gauge group. The resulting solutions preserve eight supercharges and SO(2)× SO(2) or SO(2)_diag symmetries and are expected to be dual to N=2 SCFTs in three dimensions arising from compactifications of five-dimensional N=2 SCFT on a half-spindle. All of the solutions lie within the U(1)× U(1) subsector of the matter-coupled F(4) gauged supergravity that can be embedded in massive type IIA theory.
