“…For field strengths comparable to the magnetic masses of charged gluons, the formation of a gluon-vortex state can take place [15,16] and, as explained in [10], the vortex formation corresponds to a phase transition from a magnetic-CFL to a Paramagnetic-CFL phase. There are many other effects produced by a strong magnetic fields in combination with superconductivity [17][18][19][20][21][22], such as the BEC-BCS crossover [1,[23][24][25][26] and the modification of chiral inhomogeneous phases [27][28][29][30].…”

In this article, we calculate the magnetization and other thermodynamical quantities for strongly magnetized quark matter within the Nambu-Jona-Lasinio model at zero temperature. We assume two scenarios: chemically equilibrated charge neutral matter present in the interiors of compact stars and zero-strangeness isospin-symmetric matter created in nuclear experiments. We show that the magnetization oscillates with density but in a much more smooth form than what was previously shown in the literature. As a consequence, we do not see the unphysical behavior in the pressure in the direction perpendicular to the magnetic field that was previously found. Finally, we also analyze the effects of a vector interaction on our results.
