In the NJL model with exact phase-space diagonalization, magnetic catalysis of the chiral condensate quenches the tachyonic instability of the spin-aligned rho+ by driving the 2M threshold above the Zeeman-lowered mass, preventing condensation.

abstract
We compute the electromagnetic fields generated in heavy-ion collisions by using the HIJING model. Although after averaging over many events only the magnetic field perpendicular to the reaction plane is sizable, we find very strong magnetic and electric fields both parallel and perpendicular to the reaction plane on the event-by-event basis. We study the time evolution and the spatial distribution of these fields. Especially, the electromagnetic response of the quark-gluon plasma can give non-trivial evolution of the electromagnetic fields. The implications of the strong electromagnetic fields on the hadronic observables are also discussed.

Stationary solutions of the Dirac equation for fermions in an external electric field exhibit asymptotic oscillations, absence of bound states in infinite systems, and deconfining behavior when electric coupling exceeds confinement coupling, with MIT bag boundaries enabling finite-system confinement
The Weyl anomaly induces a new non-dissipative current in accelerated fluids that fixes the electromagnetic-acceleration coupling at second order in hydrodynamics.
Continuum-extrapolated lattice simulations show monotonic magnetic catalysis in chiral condensates, non-monotonic charged-meson mass response, and valence-quark dominance at zero temperature up to eB ≈ 1.2 GeV².
Photon emission rate and electromagnetic energy loss from rescattering in magnetized QGP are derived in the high-energy limit, showing slight suppression over broad jet energies.
Proposes that the relative polarization of tau+ and tau- decay products in UPCs, aligned to the magnetic field, provides a sensitive probe for CP violation.
Coupled BDNK MHD evolution in boost-invariant flow enhances cooling and suppresses the low-mass dilepton spectrum via magnetic-thermal feedback.
Neutral mesons conserve continuous transverse momenta in magnetic fields while charged mesons exhibit quantized transverse dynamics, with high-spin charged mesons stabilized by cancellation of internal zero-point energy against orbital Zeeman energy.
The review summarizes developments in spin hydrodynamics, polarization from spin-vorticity coupling, pseudo-gauge freedom, and heavy-flavor spin dynamics in relativistic systems.
