Quark deconfinement in high-mass neutron stars
(American Physical Society, 2014-01)
In this paper, we explore whether or not quark deconfinement may occur in high-mass neutron stars such as J1614 - 2230 (1.97±0.04M) and J0348 + 0432 (2.01±0.04M). Our study is based on a nonlocal extension of the SU(3) ...
Magnetars as highly magnetized quark stars: An analytical treatment
(IOP Publishing, 2011-06)
We present an analytical model of a magnetar as a high-density magnetized quark bag. The effect of strong magnetic fields (B > 5 × 10^16 G) in the equation of state is considered. An analytic expression for the mass-radius ...

Quark-hybrid matter in the cores of massive neutron stars
(American Physical Society, 2013-01)
Using a nonlocal extension of the SU(3) Nambu-Jona-Lasinio model, which reproduces several of the key features of quantum chromodynamics, we show that mixed phases of deconfined quarks and confined hadrons (quark-hybrid ...
Phase structure of cold magnetized quark matter within the SU(3) NJL model
(American Physical Society, 2014-08)
The possible different phases of homogeneous cold quark matter in the presence of a finite magnetic field and chemical potential are obtained within the SU(3) NJL model for two parameter sets often used in the literature. ...
Magnetized color superconducting cold quark matter within the SU (2)f NJL model: A novel regularization scheme
(American Physical Society, 2015-10)
The influence of intense magnetic fields on the behavior of color superconducting cold quark matter is investigated using an SU(2)f Nambu-Jona-Lasinio-type model for which a novel regulation scheme is introduced. In such ...
Decoupling of quark condensate from the effective nucleon mass at high density (ϱ) and temperature (T)
(1995-11-16)
It is found that the quark condensate 〈qq〉, instead of decreasing at high ρ{variant}, as commonly expected, starts to increase after a certain density (∼ 1.5ρ{variant}0 - in standard relativistic nuclear matter models. ...
