| Titre | Analytic continuation of TBA equations |
| Résumé | TBA equations encode the energy levels of integrable quantum field theories in finite volume. If these equations are continued through complex values of the coupling constant, different energy levels can be connected. This talk will explain how this goes, and describe old and ongoing work to explore the resulting Riemann surface, looking at the Yang-Lee and sinh-Gordon models. |
