Spontaneous Spin Polarization in Dense Quark Matter Reexamined
Carlisson Miller, Rodolfo Casana, Manoel M. Ferreira +1
The phase structure of strongly interacting matter at high baryon density remains an open problem in QCD, with important implications for the internal structure and magnetic proper…
Causality violation and the speed of sound of hot and dense quark matter in the Nambu--Jona-Lasinio model
Arthur E. B. Pasqualotto, Ricardo L. S. Farias, William R. Tavares +2
The Nambu--Jona-Lasinio model is widely used to study strong-interaction phenomena in vacuum and quark matter. Since the model is nonrenormalizable, one needs to work within a spec…
Study of meson interactions via femtoscopic correlations
Isabela M. Silvério, Sandra S. Padula, Gastão I. Krein
Femtoscopy is a powerful tool that can be used to investigate the space-time dimensions of the region from which the particles are emitted. When applied to high energy collisions t…

William R. Tavares, Ricardo L. S. Farias, Sidney S. Avancini +3
We use a three-flavor Nambu--Jona-Lasinio model to study the thermodynamics of strange quark matter under a strong magnetic field. The model Lagrangian features flavor SU(3) four-q…
Nonequilibrium Dynamics of the Chiral Quark Condensate under a Strong Magnetic Field
Gastao Krein, Carlisson Miller
Strong magnetic fields impact quantum-chromodynamics (QCD) properties in several situations; examples include the early universe, magnetars, and heavy-ion collisions. These example…

We construct a quark target model (QTM) to incorporate intrinsic glue into effective low-energy models of QCD, which often contain only quark degrees of freedom. This method guaran…

G. Krein, T. C. Peixoto
We study the prospects of using femtoscopic low-momentum correlation measurements at the Large Hadron Collider to access properties of the J/psi-nucleon interaction. The QCD multip…
