Effect of Quark Dimension Reduction on Goldstone Mode in Magnetic Field
read the original abstract
The meson static properties are investigated in Pauli-Villars regularized Nambu--Jona-Lasinio model in strong magnetic field. The quark dimension reduction leads to not only the magnetic catalysis effect on chiral symmetry restoration but also a sudden jump of the mass of the Goldstone mode at the Mott transition temperature.

Effect of anomalous magnetic moment of quarks on the phase structure and mesonic properties in the NJL model
In the two-flavor NJL model with anomalous magnetic moment of quarks, external magnetic field produces inverse magnetic catalysis and a magnetic-field-dependent drop in the Mott temperature for the Goldstone mode.

Spectral function for pions in magnetic field
Pion spectral functions in magnetic fields develop multi-peak structures for neutral pions from Landau levels and Landau cuts for charged pions, with decay widths narrowing at higher temperatures indicating increased ...
