Abstract
We point out some directions for potential generalizations of Calogero-type systems. In particular, we demonstrate that a many-matrix model gives rise, upon Hamiltonian reduction, to a multidimensional version of the Calogero—Sutherland—Moser model and its spin generalizations. Some simple solutions of these models are demonstrated by solving the corresponding matrix equations. We also show that a supersymmetric system of spinless particles in which supersymmetry is realized through exchange operators exhibits reflectionless two-body scattering for arbitrary prepotential. The exchange-Calogero system is the simplest example, but it is conjectured that appropriate three-body forces would make all such systems integrable.
