From Threshold Crossing to Wave-function Renormalization: Defining the Pion Mott Temperature in a Magnetic Field

Sidney S. Avancini, Maximo Coppola, Dyana C. Duarte +3

We investigate the dissociation of the neutral pion in hot magnetized quark matter within the two-flavor Nambu--Jona-Lasinio model. At zero magnetic field, the Mott temperature is…

Robust Finite-Momentum Instabilities in Dense Matter

André G. da Silva, Ricardo L. S. Farias, Theo Motta +1

The predicted extent of inhomogeneous chiral phases in effective models of quantum chromodynamics is notoriously sensitive to ultraviolet regularization. We show that this sensitiv…

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 s…
