Phase Transition in Simplest Plasma Models

TL;DR

This paper investigates first-order phase transitions in simple plasma models lacking charge correlations, predicting discontinuities in charge profiles that suggest phase transition phenomena under certain approximations.

Contribution

It introduces a new analysis of phase transitions in plasma models without charge correlations, highlighting predicted discontinuities in charge distributions.

Findings

Discontinuities in equilibrium charge profiles are predicted.

Phase transition phenomena are identified in simplified plasma models.

Anomalies are linked to specific approximations used in the models.

Abstract

The properties of the first-order phase transition in a set of plasma models with common feature - absence of individual correlations between charges of op-posite sign, have been studied. Predicted discontinuities in equilibrium non-uniform charge profiles have been calculated for the case of electron distribution in atomic cell and some other similar situations. These anomalies appear when some simple approximations are used and they may be naturally interpreted in terms of discussed phase transition
