The anisotropic λ-deformed SU(2) model is integrable
Konstantinos Sfetsos, Konstantinos Siampos
The all-loop anisotropic Thirring model interpolates between the WZW model and the non-Abelian T-dual of the anisotropic principal chiral model. We focus on the SU(2) case and we p…

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…
