The most general -deformation of CFTs and integrability
George Georgiou, Konstantinos Sfetsos
We show that the CFT with symmetry group consisting of WZW models based on the same group , but at arbitrary integer levels,…
Weyl anomaly and the -function in -deformed CFTs
Eftychia Sagkrioti, Konstantinos Sfetsos, Konstantinos Siampos
For a general -deformation of current algebra CFTs we compute the exact Weyl anomaly coefficient and the corresponding metric in the couplings space geometry. By incorporating t…
Novel all loop actions of interacting CFTs: Construction, integrability and RG flows
George Georgiou, Konstantinos Sfetsos
We construct the all loop effective action representing, for small couplings, simultaneously self and mutually interacting current algebra CFTs realized by WZW models. This non-tri…
The exact -function in integrable -deformed theories
George Georgiou, Pantelis Panopoulos, Eftychia Sagkrioti +2
By employing CFT techniques, we show how to compute in the context of λ-deformations of current algebras and coset CFTs the exact in the deformation parameters C-function for a wid…
Non-Abelian T-duality and Modular Invariance
Benjo Fraser, Dimitrios Manolopoulos, Konstantinos Sfetsos
Two-dimensional -models corresponding to coset CFTs of the type admit a zoom-in limit invol…
T-duality and high-derivative gravity theories: the BTZ black hole/string paradigm
Jose D. Edelstein, Konstantinos Sfetsos, J. Anibal Sierra-Garcia +1
We show that the temperature and entropy of a BTZ black hole are invariant under T-duality to next to leading order in , being the scale suppressing higher-…
