Conformal line defects from matter-coupled 5D N=4 gauged supergravity
- 1Chulalongkorn University
Abstract
We study a number of holographic solutions describing conformal line defects within N=2 N = 2 SCFTs from matter-coupled N=4 N = 4 gauged supergravity in five dimensions. For SO(2)D× SO(3) S O ( 2 ) D × S O ( 3 ) gauge group, the gauged supergravity admits two supersymmetric AdS5 A d S 5 vacua with N=4 N = 4 and N=2 N = 2 unbroken supersymmetries. It turns out that only solutions that are asymptotic to the N=4 N = 4 vacuum are possible leading to line defects within the dual N=2 N = 2 SCFT. In gauged supergravity with SO(2)× ISO(3) S O ( 2 ) × I S O ( 3 ) gauge group, we find similar solutions with the N=2 N = 2 SCFT appearing in the IR while the UV field theories correspond to six-dimensional N=(0,2) N = ( 0 , 2 ) field theories arising from M5-branes wrapped on a hyperbolic space H2 H 2 . The solution with SO(2)× SO(3) S O ( 2 ) × S O ( 3 ) symmetry is also uplifted to eleven dimensions via a consistent truncation on H2× S4 H 2 × S 4 . Finally, for gauged supergravity with SO(2)× SO(3)× SO(3) S O ( 2 ) × S O ( 3 ) × S O ( 3 ) gauge group that admits two N=4 N = 4 supersymmetric AdS5 A d S 5 vacua, we find a solution describing a line defect that interpolates between these two vacua as well as a solution with only one asymptotic AdS5 A d S 5 geometry.

AB - We study a number of holographic solutions describing conformal line defects within N=2 N = 2 SCFTs from matter-coupled N=4 N = 4 gauged supergravity in five dimensions.

In gauged supergravity with SO(2)× ISO(3) S O ( 2 ) × I S O ( 3 ) gauge group, we find similar solutions with the N=2 N = 2 SCFT appearing in the IR while the UV field theories correspond to six-dimensional N=(0,2) N = ( 0 , 2 ) field theories arising from M5-branes wrapped on a hyperbolic space H^2 H 2 . The solution with SO(2)× SO(3) S O ( 2 ) × S O ( 3 ) symmetry is also uplifted to eleven dimensions via a consistent truncation on H^2× S^4 H 2 × S 4 . Finally, for gauged supergravity with SO(2)× SO(3)× SO(3) S O ( 2 ) × S O ( 3 ) × S O ( 3 ) gauge group that admits two N=4 N = 4 supersymmetric AdS_5 A d S 5 vacua, we find a solution describing a line defect that interpolates between these two vacua as well as a solution with only one asymptotic AdS_5 A d S 5 geometry.
