Comments on non-Abelian T-duals and their holographic description

Abstract

We present three different Type IIB AdS 4 Supergravity solutions, derived using the electrostatic-like problem formalism which preserves 8 Poincaré Supercharges. Two of these solutions correspond to the Abelian and non-Abelian T-duals of a Type IIA background, obtained from the dimensional reduction of 11D AdS 4 × S 7 Supegravity. The third solution is a new background with some special properties. We compute the Page charges in each case, and provide brane set-up descriptions of the geometries. Also, we argue that the non-Abelian T-dual can be understood as a zoom-in of a more general background with a well defined holographic dual.

Wilson loops for 5d and 3d conformal linear quivers

“…In the case of three dimensional N = 4 SCFTs, the field theoretical aspects of linear quivers presented in [2] were discussed holographically in [3][4][5][6][7][8][9] among other works. The case of N = 1 five dimensional linear quiver SCFTs (with eight Poincaré supercharges) was initially analysed holographically in [10].…”
