Abstract

Abstract: With numerical method we obtained the location of minimum value of Gibbs function in configuration space for two dimensional hard disk system, and the equation of state and phase diagram of the model, we found that only the 6-atom solid phase and liquid phase can be exist in the model. The wrong method and conclusion of previcus work have been corrected.

Key words: two-dimensional hard disk system, phase transition, Gibbs free energy, equation of state
