Type-II backgrounds from deformed coset CFTs

A bstract 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.
