Negative specific heat in a Lennard-Jones-like gas with long-range interactions

Statistical Mechanics 2007-05-23 v2

Abstract

We study, through molecular dynamics, a conservative two-dimensional Lennard-Jones-like gas (with attractive potential rα\propto r^{-\alpha}). We consider the effect of the range index α\alpha of interactions, number of particles, total energy and particle density. We detect negative specific heat when the interactions become long-ranged (0α/d<10\le \alpha/d<1).
