Kinetics of Phase Transitions in Quark Matter

TL;DR

This paper investigates the kinetics of chiral phase transitions in quark matter, highlighting how inertial effects influence domain growth and the crossover from inertial to diffusive regimes.

Contribution

It introduces a phenomenological Ginzburg-Landau model to analyze inertial effects on phase transition kinetics in quark matter.

Findings

Domain growth exhibits a crossover from inertial to diffusive regimes.

Inertial regime follows $L(t) o t ( ext{ln} t)^{1/2}$ scaling.

Diffusive regime follows $L(t) o t^{1/2}$ scaling.

Abstract

We study the kinetics of chiral transitions in quark matter using a phenomenological framework (Ginzburg-Landau model). We focus on the effect of inertial terms on the coarsening dynamics subsequent to a quench from the massless quark phase to the massive quark phase. The domain growth process shows a crossover from a fast inertial regime [with $L(t) \sim t (\ln t)^{1/2}$] to a diffusive Cahn-Allen regime [with $L(t)\sim t^{1/2}$].
