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…
Isometries, gaugings and N=2 supergravity decoupling
Ignatios Antoniadis, Jean-Pierre Derendinger, P. Marios Petropoulos +1
We study off-shell rigid limits for the kinetic and scalar-potential terms os a single N=2 hypermultiplet. In the kinetic term, these rigid limits establish relations between four-…
The classical Yang-Baxter equation and the associated Yangian symmetry of gauged WZW-type theories
Georgios Itsios, Konstantinos Sfetsos, Konstantinos Siampos +1
We construct the Lax-pair, the classical monodromy matrix and the corresponding solution of the Yang--Baxter equation, for a two-parameter deformation of the Principal chiral model…
