“…[10,11]. Such a scheme has been recently applied in several works [12][13][14][15][16][17][18] and, in particular, it has been shown to avoid nonphysical oscillations in the context of magnetized quark matter in the presence of color superconductivity [19][20][21][22]. The procedure follows the steps of the dimensional regularization prescription of QCD, performing a sum over all Landau levels in the vacuum term.…”

We study the regularization dependence of the Nambu-Jona-Lasinio model (NJL) predictions for some properties of magnetized quark matter at zero temperature (and baryonic density) in the mean field approximation. The model parameter dependence for each regularization procedure is also analyzed in detail. We calculate the average and difference of the quark condensates using different regularization methods and compare with recent lattice results. In this context, the reliability of the different regularization procedures is discussed.

“…This motivates us to investigate the behavior of thermoelectric transport coefficients within the NJL model which takes into account the medium dependence of quark and meson masses. This model has been used to study different transport properties of quark matter at high temperatures [6,31,81,82] and high densities [83][84][85][86][87][88][89][90].…”

A thermal gradient and/or a chemical potential gradient in a conducting medium can lead to an electric field, an effect known as thermoelectric effect or Seebeck effect. In the context of heavy-ion collisions, we estimate the thermoelectric transport coefficients for quark matter within the ambit of the Nambu-Jona Lasinio (NJL) model. We estimate the thermal conductivity, electrical conductivity, and the Seebeck coefficient of hot and dense quark matter. These coefficients are calculated using the relativistic Boltzmann transport equation within relaxation time approximation. The relaxation times for the quarks are estimated from the quark-quark and quark-antiquark scattering through in-medium meson exchange within the NJL model.

“…There are many other interesting phenomena that we will hereby not address, like cold quark matter and compact star phenomenology, where NJL models play an important role in the determination of the phase diagram in dense magnetized matter, BEC-BCS or color superconductivity [53,54], the role of the quark anomalous magnetic moment on the thermodynamic properties of mesons immersed in a magnetic field [55] or the magnetic field effects on electromagnetic probes in heavy-ion collisions such as the dilepton production rate [56]. We will restrict the discussion to the description of the simultaneous temperature, baryon chemical potential and magnetic field dependence of the chiral CEP.…”

We review the main features of the QCD phase diagram description, at finite temperature, baryon density and in the presence of a magnetic field, from the point of view of effective models, whose main ingredient is chiral symmetry. We concentrate our attention on two of these models: The linear sigma model with quarks and the Nambu-Jona-Lasinio model. We show that a main ingredient to understand the characteristics of the phase transitions is the inclusion of plasma screening effects that capture the physics of collective, long-wave modes, and thus describe a prime property of plasmas near transition lines, namely, long distance correlations. Inclusion of plasma screening makes possible to understand the inverse magnetic catalysis phenomenon even without the need to consider magnetic field-dependent coupling constants. Screening is also responsible for the emergence of a critical end point in the phase diagram even for small magnetic field strengths. Although versatile, the NJL model is also a more limited approach since, being a non-renormalizable model, a clear separation between pure vacuum and medium effects is not always possible. The model cannot describe inverse magnetic catalysis unless a magnetic field dependent coupling is included. The location of the critical end point strongly depends on the choice of the type of interaction and on the magnetic field dependence of the corresponding coupling. Overall, both models provide sensible tools to explore the properties of magnetized, strongly interacting matter. However, a cross talk among them as well as a consistent physical approach to determine the model parameters is much needed.
