Fine Particles as Solute in Fine Particle (Dusty) Plasmas: Phase Separation and Diagram

TL;DR

This paper investigates phase separation in dusty plasmas with fine particles acting as solutes, presenting phase diagrams and highlighting significant density differences between coexisting phases.

Contribution

It extends previous work by analyzing phase separation and critical points of fine particles in plasmas, providing detailed phase diagrams and density comparisons.

Findings

Phase separation is possible in dusty plasmas with fine particles.

Coexisting phases can differ in particle density by nearly an order of magnitude.

Phase diagrams illustrate the conditions for phase coexistence.

Abstract

Analysis has been made on a possibility of phase separation and critical point as a solution of fine particles in plasmas, extending the previous work which pointed out this as one of two such possibilities. Fine particles are treated as a solute in the solvent of weakly coupled plasmas of electrons and ions. Examples of phase diagram have been obtained and coexisting phases are shown to have fine particles which differ in densities by almost one order of magnitude.
