Title: The holographic dual of the Omega-background
Date: Tue, Mar 19, 2019, 13:15 - 14:30
Place: Seminar Room A
Abstract: We find an explicit supergravity background dual to the
Omega-deformation of a four-dimensional N=2 SCFT on R^4. The solution can
be constructed in the five-dimensional N=4+ gauged supergravity and has a
nontrivial self-dual 2-form. When uplifted to type IIB supergravity the
background is a deformation of AdS5xS5 which preserves 24 supercharges. We
also discuss generalizations of this solution corresponding to turning on a
vacuum expectation value for a scalar operator in the dual SCFT.
