Penrose limits of Abelian and non-Abelian T-duals of and their field theory duals
Georgios Itsios, Horatiu Nastase, Carlos Núñez +2
We consider the backgrounds obtained by Abelian and non-Abelian T-duality applied on . We study geodesics, calculate Penrose limits and find the associated plane-w…
Integrable deformations of the coset CFTs
Konstantinos Sfetsos, Konstantinos Siampos
We study the effective action for the integrable -deformation of the coset CFTs. For unequal levels theses models do not fall into the gener…
Integrable flows between exact CFTs
George Georgiou, Konstantinos Sfetsos
We explicitly construct families of integrable -model actions smoothly interpolating between exact CFTs. In the ultraviolet the theory is the direct product of two current algeb…
Double and cyclic -deformations and their canonical equivalents
George Georgiou, Konstantinos Sfetsos, Konstantinos Siampos
We prove that the doubly lambda-deformed sigma-models, which include integrable cases, are canonically equivalent to the sum of two single lambda-deformed models. This explains the…
Quantum aspects of doubly deformed CFTs
George Georgiou, Eftychia Sagkrioti, Konstantinos Sfetsos +1
We study quantum aspects of the recently constructed doubly lambda-deformed sigma-models representing the effective action of two WZW models interacting via current bilinears. We s…
