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…
Chiral first order phase transition at finite baryon density and zero temperature from self-consistent pole masses in the linear sigma model with quarks
Alejandro Ayala, Bruno El-Bennich, Ricardo L. S. Farias +4
We use the two-flavor Linear Sigma Model with quarks as an effective description of QCD to investigate the nature of the chiral phase transition at finite baryon chemical potential…
Meson mixing effects on the speed of sound in isospin-imbalanced matter
Alejandro Ayala, Bruno S. Lopes, Ricardo L. S. Farias +1
We explore isospin imbalanced strongly interacting matter within the two-flavor Linear Sigma Model with quarks, an effective model for low-energy QCD. At one loop order, including…
Violation of the Conformal Limit at Finite Density: Insights from Effective Models and Lattice QCD
Francisco X. Azeredo, Arthur E. B. Pasqualotto, Bruno S. Lopes +2
In this work, we discuss recent results obtained with the application of the medium separation scheme (MSS) in different contexts where a clear violation of the conformal limit for…
Speed of sound peak in isospin QCD: a natural prediction of the Medium Separation Scheme
Bruno S. Lopes, Dyana C. Duarte, Ricardo L. S. Farias +1
We present predictions for the zero-temperature equation of state at finite isospin density using the Nambu-Jona-Lasinio (NJL) model within the medium separation scheme (MSS) -- a…
On the origin of the peak of the sound velocity for isospin imbalanced strongly interacting matter
Alejandro Ayala, Bruno S. Lopes, Ricardo L. S. Farias +1
We study the properties of a system composed of strongly interacting matter with an isospin imbalance, using as an effective description of QCD the two-flavor Linear Sigma Model wi…
