Kerr-Schild perturbations of coset CFTs as scale invariant integrable -models
Georgios Itsios, Konstantinos Sfetsos, Konstantinos Siampos
Kerr-Schild perturbations in General Relativity provide a fruitful way of constructing new exact solutions starting from known ones, elucidating also the structure of the spacetime…
Novel integrable interpolations
Georgios Itsios, Konstantinos Sfetsos, Konstantinos Siampos
A novel class of integrable -models interpolating between exact coset conformal field theories in the IR and hyperbolic spaces in the UV is constructed. We demonstrate the relat…
On the stability of backgrounds with -deformed factors
Georgios Itsios, Pantelis Panopoulos, Konstantinos Sfetsos +1
We investigate the stability of the non-supersymmetric solutions of type-IIB supergravity having an unwarped factor and -deformed subspaces found in arXiv:1911.12371. Amon…
-deformations in the upper-half plane
Konstantinos Sfetsos, Konstantinos Siampos
We formulate -deformed -models as QFTs in the upper-half plane. For different boundary conditions we compute correlation functions of currents and primary operators, exactly…
Integrable -deformations of the Euclidean black string
Sibylle Driezen, Konstantinos Sfetsos
Non-trivial outer algebra automorphisms may be utilized in -deformations of (gauged) WZW models thus providing an efficient way to construct new integrable models. We provide tw…
