Abstract:
We discuss the correspondence between models solved by the Bethe ansatz and classical integrable systems of the Calogero type. We illustrate the correspondence by the simplest example of the inhomogeneous asymmetric six-vertex model parameterized by trigonometric (hyperbolic) functions.
Keywords:
six-vertex model, Ruijsenaars–Schneider system of particles, quantum–classical correspondence.
