N=2 superconformal Newton-Hooke algebra and many-body mechanics
arXiv:0906.5509 · doi:10.1016/j.physletb.2009.09.037
Abstract
A representation of the conformal Newton-Hooke algebra on a phase space of n particles in arbitrary dimension which interact with one another via a generic conformal potential and experience a universal cosmological repulsion or attraction is constructed. The minimal N=2 superconformal extension of the Newton-Hooke algebra and its dynamical realization in many-body mechanics are studied.
