Unstable State in Argon by Constant Temperature and Volume Molecular Dynamics Simulation

Abstract

Unstable state in argon was studied by constant temperature and volume molecular dynamics simulation. The number of molecules in the basic cell was 864. The Lennard-Jones potential function was assumed. The obtained pressure and internal energy were consistent with the reported equation of state which was determined by the simulation data in the stable state. Pressure had van der Waals loop in the unstable state.
