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 λ-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.
