Superconducting quark matter in the Chromodielectric Model
(2004-12-02)
In this work we study the strange quark matter in an extented version of the Chromodielectric Model (CDM) with a BCS quark pairing implemented, and analyze the superconducting color flavor locked (CFL) phase. We compare ...
Neutrino emissivity in the color superconducting quark‐hadron‐mixed phase
(John Wiley & Sons Inc, 2019)
The tremendously high pressures that exist in the cores of neutron stars may break up neutrons, protons plus other hadronic particles into their quark constituents. This transition from hadronic matter to quark matter could ...
Velocidade do som em matéria quente e densa de quarks
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2022-04-25)
In this work two different approaches to the regularization of thermal integrals in the NJL
(Nambu–Jona-Lasinio) SU(2) model are investigated from the phenomenological point of
view. Showing the usefullness of the speed ...
Quark matter and meson properties in a Nonlocal SU(3) chiral quark model at finite temperature
(SP MAIK Nauka/Interperiodica, 2012-06)
We study the finite temperature behavior of light scalar and pseudoscalar meson properties in the context of a three-flavor nonlocal chiral quark model. The model includes mixing with active strangeness degrees of freedom, ...
Surface tension and curvature energy of quark matter in the Nambu-Jona-Lasinio model
(American Physical Society, 2013-10)
In this article we study the surface tension and the curvature energy of three-flavor quark matter in equilibrium under weak interactions within the Nambu-Jona-Lasinio model. We include the effect of color superconductivity ...
Quark matter in neutron stars
(Springer, 2020)
The nonlocal three-flavor Nambu-Jona-Lasinio model is used to study quark deconfinement in the cores of neutron stars (NSs). The quark-hadron phase transition is modeled using both the Maxwell construction and the Gibbs ...
Transport properties and equation of state of quark-nuclear matter
