Chiral symmety breaking in 3-flavor Nambu-Jona Lasinio model in magnetic background

TL;DR

This paper investigates how magnetic fields influence chiral symmetry breaking in a 3-flavor NJL model at finite temperature and density, revealing that magnetic fields enhance condensates at finite temperature but lower the critical chemical potential at zero temperature.

Contribution

It provides a detailed analysis of magnetic field effects on chiral symmetry breaking in a 3-flavor NJL model, including explicit ground state structure and finite temperature/density considerations.

Findings

Magnetic field enhances condensates at finite temperature.

Critical chemical potential decreases with increasing magnetic field at zero temperature.

Ground state structure includes quark and antiquark condensates.

Abstract

Effect of magnetic field on chiral symmetry breaking in a 3-flavor Nambu Jona Lasinio (NJL) model at finite temperature and densities is considered here using an explicit structure of ground state in terms of quark and antiquark condensates. While at zero chemical potential and finite temperature, magnetic field enhances the condensates, at zero temperature, the critical chemical potential decreases with increasing magnetic field.
