QCD Vacuum as Domain Wall Network

TL;DR

This paper explores a domain wall network model of the QCD vacuum, examining how strong electromagnetic fields can induce vacuum polarization effects that potentially trigger deconfinement, advancing understanding of confinement and chiral symmetry breaking.

Contribution

It introduces a domain wall network framework for the QCD vacuum and analyzes electromagnetic field effects on vacuum polarization and deconfinement.

Findings

Vacuum polarization by strong electromagnetic fields can trigger deconfinement.

The domain wall network model provides a new perspective on confinement and chiral symmetry breaking.

Electromagnetic effects are significant in QCD vacuum dynamics.

Abstract

Domain model of confinement, chiral symmetry breaking and hadronization is based on description of QCD vacuum gluon configurations as an ensemble of almost everywhere homogeneous Abelian (anti-)self-dual fields. The ensemble can be explicitly constructed as domain wall network. We shortly overview this approach and within this framework discuss the effects of QCD vacuum polarization by strong electromagnetic fields. It is stressed that such polarization effects can play the role of trigger for deconfinement.
