Title: Supergravity realisations of λ-models

Abstract: λ-models are a family of integrable deformations of two-dimensional CFTs interpolating between the (gauged) Wess-Zumino-Witten model and the non-Abelian T-dual of a Principal Chiral Model. After deriving an action for such models, I will discuss how these constructions can be used to generate solutions of type-II supergravity that include an undeformed Anti-de Sitter factor. This talk is based on my recent paper 2512.06091.
