Magnetic catalysis and Hall conductivity of excitonic insulators in a planar four-Fermi model
William R. Tavares, Rudnei O. Ramos, Nei Lopes
We study the effects of a perpendicular magnetic field on the excitonic insulator (EI) phase in the semiconductor regime using an extended planar four-Fermi model. Within the large…
Dense and Cold Magnetized Quark Matter: A Review of Magnetic-Field-Independent Regularization and the Medium Separation Scheme
Francisco X. Azeredo, Dyana C. Duarte, Ricardo L. S. Farias +3
We present a comprehensive review of regularization schemes for magnetized dense quark matter within effective models of quantum chromodynamics, focusing on the Magnetic-Field-Inde…
Two-flavor chirally imbalanced quark matter beyond large
André G. da Silva, Dyana C. Duarte, Ricardo L. S. Farias +3
We investigate a chirally imbalanced medium in the context of the two-flavor Nambu--Jona-Lasinio model using both the large- (LN) and beyond large- (BLN) approximations.…
Chiral and deconfinement transitions in spin-polarized quark matter
Ricardo L. S. Farias, William R. Tavares
We investigate the influence of spin polarization in strongly interacting matter by introducing a finite spin potential, , which effectively controls the spin density of the…
Thermomagnetic effects on light pseudo-scalar meson masses within the SU(3) Nambu-Jona--Lasinio model
Máximo Coppola, William R. Tavares, Sidney S. Avancini +2
We calculate the screening masses of pseudoscalar mesons in a hot and strongly magnetized medium within the framework of the SU(3) Nambu-Jona--Lasinio model, using a magnetic field…
Chiral vortical catalysis constrained by LQCD simulations
Rodrigo M. Nunes, Ricardo L. S. Farias, William R. Tavares +1
Evidences of vortical effects have been recently found by experiments in heavy ion collisions, instigating new insights into the phase diagram of quantum chromodynamics (QCD). Cons…
