Chiral soliton lattice phase in warm QCD

TL;DR

This paper investigates the phase diagram of QCD under magnetic fields and temperature, revealing that the chiral soliton lattice phase is stabilized by thermal fluctuations and can persist near chiral symmetry restoration.

Contribution

It demonstrates that the anomaly-induced chiral soliton lattice phase is stabilized by thermal effects within chiral perturbation theory at next-to-leading order.

Findings

Chiral soliton lattice phase is stabilized by thermal fluctuations.

CSL phase can survive up to chiral symmetry restoration temperatures.

Analysis conducted within next-to-leading order chiral perturbation theory.

Abstract

We analyze the phase diagram of quantum chromodynamics at low-to-moderate temperature, baryon chemical potential and external magnetic field within chiral perturbation theory at next-to-leading order of the derivative expansion. Our main result is that the anomaly-induced chiral soliton lattice (CSL) phase is stabilized by thermal fluctuations. As a consequence, the CSL state may survive up to temperatures at which chiral symmetry is restored.
