Critical behavior of one-component system with Yukawa interaction potential

TL;DR

This paper demonstrates the existence of a liquid-gas phase transition in a one-component Yukawa system, determines the critical exponent, and relates potential parameters to critical thermodynamic values.

Contribution

It provides the first analysis of critical behavior and phase transition parameters for a one-component Yukawa interaction system.

Findings

Liquid-gas phase transition confirmed in Yukawa systems

Critical exponent β determined

Relations between Yukawa potential parameters and critical values established

Abstract

It is shown that the liquid-gas phase transition exists in one-component system with potential Yukawa interaction. The value of the critical exponent $\beta$ of the order parameter is found. The relation between the potential parameters of Yukawa interaction and critical values of density, temperature and pressure is obtained. PACS: 51.30.+i: 64.10.+h; 05.70.Ce: 05.70.Fh; 05.70.Jk
