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…
The Robinson-Trautman spacetime and its holographic fluid
Luca Ciambelli, Anastasios C. Petkou, P. Marios Petropoulos +1
We discuss the holographic reconstruction of four-dimensional asymptotically anti-de Sitter Robinson-Trautman spacetime from boundary data. We use for that a resummed version of th…
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…
