Type-II backgrounds from deformed coset CFTs

Abstract

We construct a plethora of type-II supergravity solutions featuring AdS factors in their geometries, derived from integrable deformations of coset CFTs. Specifically, we uplift the $\lambda$-deformed models of $SO(4{)}_k/SO(3{)}_k$ and $SO(5{)}_k/SO(4{)}_k$, including the non-compact version of the latter. Requiring reality for the backgrounds imposes bounds on the deformation parameter. As a result, some of the solutions do not admit non-Abelian T-dual limit.
