“…Our calculations here are qualitatively consistent with the results of other NJL models [39][40][41][42][43][44][45][46], hadron models [35][36][37][38] and lattice QCD simulations [34,[51][52][53].…”

“…When the magnetic field is turned off, there will be no more discrete energy levels, the integration in the polarization function d 3 p/(2E f − ω) ∼ pdp becomes finite at the threshold, and the mass jumps disappear automatically, see the upper panel of Fig.2. It is also necessary to point out that, in hadron models like chiral perturbation theory, linear sigma model and bosonized NJL model where hadrons are taken as elementary particles, the pion mass changes with temperature continuously [35][36][37][38]45].…”

“…For instance, for neutral hadrons, they do not have any interaction with electromagnetic fields, if we neglect the charged constituent quarks. Meson properties in electromagnetic fields are widely studied in effective models at hadron level, such as in chiral perturbation theory [35][36][37] and linear sigma model [38], and at quark level, such as in Nambu-Jona-Lasinio (NJL) model [39][40][41][42][43][44][45][46][47][48][49][50] and lattice QCD simulations [34,[51][52][53].…”

Pions in external magnetic field are investigated in the frame of a Pauli-Villars regularized Nambu-Jona-Lasinio model. The meson propagators in terms of quark bubbles in Ritus and Schwinger schemes are analytically derived, and pion masses are numerically calculated in the Ritus scheme. For neutral and charged pions at finite temperature, there exist respectively one and three mass jumps at the corresponding Mott transition points, due to the discrete energy levels of the two constituent quarks in magnetic field.

“…In a recent paper, Kamikado and Kanazawa (2014a) go beyond the LPA by including the wave-functional renormalization terms Z ⊥ and Z . In order to avoid the complication of having two invariants ρ and ∆ on which the effective potential U k depends, they consider the case N f = 1.…”

We review in detail recent advances in our understanding of the phase structure and the phase transitions of hadronic matter in strong magnetic fields B and zero quark chemical potentials µ f . Many aspects of QCD are described using low-energy effective theories and models such as the MIT bag model, the hadron resonance gas model, chiral perturbation theory, the Nambu-Jona-Lasinio (NJL) model, the quark-meson (QM) model and Polyakov-loop extended versions of the NJL and QM models. We critically examine their properties and applications. This includes mean-field calculations as well as approaches beyond the mean-field approximation such as the functional renormalization group (FRG). Renormalization issues are discussed and the influence of the vacuum fluctuations on the chiral phase transition is pointed out. Magnetic catalysis at T = 0 is covered as well. We discuss recent lattice results for the thermodynamics of nonabelian gauge theories with emphasis on SU (2)c and SU (3)c. In particular, we focus on inverse magnetic catalysis around the transition temperature Tc as a competition between contributions from valence quarks and sea quarks resulting in a decrease of Tc as a function of B. Finally, we discuss recent efforts to modify models in order to reproduce the behavior observed on the lattice. A. B-dependent transition temperature T0 51 B. B-dependent coupling constant 52 XI.
