Marginal deformations of 3d N=2 CFTs from AdS4 backgrounds in generalised geometry

Abstract:

We study exactly marginal deformations of 3d N = 2 CFTs dual to AdS4 solutions in eleven-dimensional supergravity using generalised geometry. Focussing on Sasaki-Einstein backgrounds, we find that marginal deformations correspond to turning on a four-form flux on the internal space at first order. Viewing this as the deformation of a generalised structure, we derive a general expression for the four-form flux in terms of a holomorphic function. We discuss the explicit examples of S7 , Q1,1,1 ...
