A new model in the Calogero-Ruijsenaars family
Abstract
Hamiltonian reduction is used to project a trivially integrable system on the Heisenberg double of SU(n,n), to obtain a system of Ruijsenaars type on a suitable quotient space. This system possesses BCn symmetry and is shown to be equivalent to the standard three-parameter BCn hyperbolic Sutherland model in the cotangent bundle limit.
