Thermodynamics of the Heisenberg XXX chain with negative spin

A bstract We study the thermodynamics of the isotropic Heisenberg XXX spin chain with negative spin, focusing on the case s = –1. The model is equivalent to the quantum lattice nonlinear Schrödinger (NLS) model and appears as an effective theory in deep inelastic scattering in hi...
