Field theory and -deformations: Expanding around the identity
George Georgiou, Konstantinos Sfetsos
We explore the structure of the -deformed -model action by setting up a perturbative expansion around the free field point corresponding to the identity group element. We inc…
AdS solutions and -deformations
Georgios Itsios, Konstantinos Sfetsos
We elevate -deformed -models into full type-II supergravity backgrounds. We construct several solutions which contain undeformed spaces, with and , as an…
Strong integrability of -deformed models
George Georgiou, Konstantinos Sfetsos, Konstantinos Siampos
We study the notion of strong integrability for classically integrable -deformed CFTs and coset CFTs. To achieve this goal we employ the Poisson brackets of the spatial Lax matr…
An exact symmetry in -deformed CFTs
George Georgiou, Eftychia Sagkrioti, Konstantinos Sfetsos +1
We consider -deformed current algebra CFTs at level , interpolating between an exact CFT in the UV and a PCM in the IR. By employing gravitational techniques, we derive the t…
String theory on the Schrodinger pp-wave background
George Georgiou, Konstantinos Sfetsos, Dimitrios Zoakos
We study string theory on the pp-wave geometry obtained by taking the Penrose limit around a certain null geodesic of the non-supersymmetric Schrodinger background. We solve for th…
Exact results from the geometry of couplings and the effective action
George Georgiou, Pantelis Panopoulos, Eftychia Sagkrioti +1
We invent a method that exploits the geometry in the space of couplings and the known all-loop effective action, in order to calculate the exact in the couplings anomalous dimensio…
