Séminaire de Physique Théorique

Integrable coupled sigma-models from affine Gaudin models
Sylvain Lacroix (Universität Hamburg)
Thursday 19 September 2019 14:00 -  Tours -  Salle 1180 (Bât E2)

Résumé :
In this seminar, I will discuss integrable systems called affine Gaudin models and their application to the study of integrable sigma models. As an introductory example, I will first discuss a simpler class of Gaudin models, the finite ones, and their relation with integrable spin chains and mechanical systems. I will then explain how to use affine Gaudin models to construct new integrable classical sigma models, by coupling together an arbitrary number of principal chiral models with Wess-Zumino terms.
