Journal ArticleDOI
Phase diagram of hot QCD in an external magnetic field: Possible splitting of deconfinement and chiral transitions
TL;DR: In this paper, the linear sigma model coupled to quarks and to Polyakov loops is used to investigate how the chiral and deconfining transitions are affected, and present a general picture for the temperature-magnetic field phase diagram.
Journal ArticleDOI
Chiral transition in a strong magnetic background
TL;DR: In this article, the modified effective potential in the linear sigma model with quarks to one loop in the MS scheme for N{sub f}=2 was shown to modify the nature and the dynamics of the chiral phase transition at finite temperature, with possible implications for noncentral heavy ion collisions at the Relativistic Heavy Ion Collider and the Large Hadron Collider.
Journal ArticleDOI
Constraining neutron star matter with QCD
TL;DR: In this article, the authors demonstrate that significant further restrictions can be placed by additionally requiring the pressure to approach that of deconfined quark matter at high densities, which turns out to be highly insensitive to the amount of quark material inside the stars.
Journal ArticleDOI
Interacting quark matter equation of state for compact stars
TL;DR: In this paper, a simple effective equation of state (EOS) for cold quark matter that consistently incorporates the effects of interactions and furthermore includes a built-in estimate of the inherent systematic uncertainties is presented.
Journal ArticleDOI
Deconfinement in the presence of a strong magnetic background: An exercise within the MIT bag model
TL;DR: In this paper, the effect of a very strong homogeneous magnetic field on the thermal deconfinement transition was studied using the simplest phenomenological approach: the MIT bag pressure for the quark-gluon plasma and a gas of pions for the hadronic sector.
