Hysteresis in the Mott Transition between Plasma and Insulating Gas

arXiv:cond-mat/9507116 · doi:10.1103/PhysRevE.52.5796

Abstract

We show that hysteresis can occur in the transition between a neutral plasma and the insulating gas consisting of neutral pairs bound by Coulomb attraction. Since the transition depends sensitively on the screening length in the plasma, regions of bistability occur in density--temperature phase space. We present numerical results which indicate where these regions occur for systems such as spin-polarized hydrogen, positronium gas, and excitons in a semiconductor.
