Molecular Dynamics Studies of Solid-Liquid Phase Transition in 2-D Yukawa Systems

We present systematic studies aimed at investigating the precise details of solid-liquid phase transition in 2-D classical many-particle systems interacting with the Yukawa potential.

Description
Summary:We present systematic studies aimed at investigating the precise details of solid-liquid phase transition in 2-D classical many-particle systems interacting with the Yukawa potential. This is done by introducing and analyzing a variety of indicators, such as the bond angular order parameter, the angular distribution of the Einstein oscillations, local angular correlations, global positional correlations, and the variation of internal energy in the vicinity of the melting temperature. Our results consequently show rapid changes around Gamma=415 for kappamacr=2 of the investigated quantities
