New integrable coset sigma models
Gleb Arutyunov, Cristian Bassi, Sylvain Lacroix
By using the general framework of affine Gaudin models, we construct a new class of integrable sigma models. They are defined on a coset of the direct product of copies of a Li…

Integrable deformations of coupled sigma-models
Cristian Bassi, Sylvain Lacroix
We construct integrability-preserving deformations of the integrable -model coupling together copies of the Principal Chiral Model. These deformed theories are obtained usin…
