Holographic line defects in F(4) gauged supergravity

Abstract

In this note we construct a solution of six-dimensional $F(4)$ gauged supergravity using $Ad{S}_2\times S^3$ warped over an interval as an ansatz. The solution is completely regular, preserves eight of the sixteen supersymmetries of the $Ad{S}_6$ vacuum and is a holographic realization of a line defect in a dual five-dimensional theory. We calculate the expectation value of the defect and the one-point function of the stress tensor in the presence of the defect using holographic renormalization.
