# Dynamical formation of center domains in quark-gluon plasma

## TL;DR

This paper investigates how center domains form dynamically in quark-gluon plasma during the deconfinement transition, using a phenomenological model fitted to lattice QCD data to understand domain formation times and structures.

## Contribution

It introduces a phenomenological model for Polyakov loop propagation to study center domain formation in quenched QCD, connecting theory with lattice data.

## Key findings

- Insights into the dynamical formation of center domains.
- Estimation of formation timescales above critical temperature.
- Observation of energy band formation along domain walls.

## Abstract

We study the formation of domain structures due to spontaneous breakdown of center symmetry at high temperatures in quenched QCD. We develop a phenomenological model for the explicit propagation of the Polyakov loop as the relevant order parameter of the deconfinement phase transition. The surface tension in the equation of motion is fit in comparison with lattice QCD data. Results give insight into the dynamical formation of center domains as well as the formation of energy bands along domain walls and let us estimate the required time to form such structures above the critical temperature.
