Abstract

Integrable deformations of the hyperbolic and trigonometric BCn Sutherland models were recently derived via Hamiltonian reduction of certain free systems on the Heisenberg doubles of SU(n, n) and SU(2n) respectively. As a step towards constructing action-angle variables for these models, we here apply the same reduction to a different free system on the double of SU(2n), and thereby obtain a novel integrable many-body model of Ruijsenaars-Schneider-van Diejen type that is in action-angle duality with the respective deformed Sutherland model.
