Density of states estimation for soft core system

Abstract

The density of states (DOSs) for the soft core system is calculated by the multicanonical molecular dynamics simulation. We found the DOS of this system has a concavity. Owing to this concavity, the probability distribution has double peaks near the temperature where the system undergoes the solid–fluid phase transition.
