Phase transition from nuclear matter to color superconducting quark matter: the effect of the isospin [PDF]

Phys.Rev.D81:094024,2010, 2010
We compute the mixed phase of nuclear matter and 2SC matter for different temperatures and proton fractions. After showing that the symmetry energy of the 2SC phase is, to a good approximation, three times larger than the one of the normal quark phase, we discuss and compare all the properties of the mixed phase with a 2SC component or a normal quark ...

Phase transition from hadronic matter to quark matter [PDF]

Phys.Rev.C75:045202,2007, 2006
We study the phase transition from nuclear matter to quark matter within the SU(3) quark mean field model and NJL model. The SU(3) quark mean field model is used to give the equation of state for nuclear matter, while the equation of state for color superconducting quark matter is calculated within the NJL model.

Neutrino Propagation In Color Superconducting Quark Matter [PDF]

Phys.Rev. D62 (2000) 103002, 2000
We calculate the neutrino mean free path in color superconducting quark matter, and employ it to study the cooling of matter via neutrino diffusion in the superconducting phase as compared to a free quark phase. The cooling process slows when quark matter undergoes a second order phase transition to a superconducting phase at the critical temperature ...

Effects of density-dependent quark mass on phase diagram of three-flavor quark matter [PDF]

Commun.Theor.Phys.45:691-696,2006, 2005
Considering the density dependence of quark mass, we investigate the phase transition between the (unpaired) strange quark matter and the color-flavor-locked matter, which are supposed to be two candidates for the ground state of strongly interacting matter.

Neutron matter - Quark matter phase transition and Quark star [PDF]

Int.J.Mod.Phys.E2:547-564,1993, 1993
We consider the neutron matter quark matter phase transition along with possible existence of hybrid quark stars. The equation of state for neutron matter is obtained using a nonperturbative method with pion dressing of the neutron matter and an analysis similar to that of symmetric nuclear matter.

Quark deconfinement in neutron star cores and the ground state of neutral matter [PDF]

Eur.Phys.J.A34:153-160,2007, 2007
Whether or not deconfined quark phase exists in neutron star cores and represents the ground state of neutral matter at moderate densities are open questions. We use two realistic effective quark models, the three-flavor Nambu-Jona-Lasinio model and the modified quark-meson coupling model, to describe the neutron star matter.

Isospin-dependent clusterization of Neutron-Star Matter [PDF]

Nucl.Phys.A789:403-425,2007, 2006
Because of the presence of a liquid-gas phase transition in nuclear matter, compact-star matter can present a region of instability against the formation of clusters. We investigate this phase separation in a matter composed of neutrons, protons and electrons, within a Skyrme-Lyon mean-field approach.

Phases of dense matter in neutron stars [PDF]

Phys.Rept. 328 (2000) 237-327, 1999
Recent equations of state for dense nuclear matter are discussed with possible phase transitions arising in neutron stars such as pion, kaon and hyperon kondensation, superfluidity and quark matter. Specifically, we treat the nuclear to quark matter phase transition, the possible mixed phase and its structure.

Is there Quark Matter in (Low-Mass) Pulsars? [PDF]

, 2008
The effect of the QCD phase transition is studied for the mass-radius relation of compact stars and for hot and dense matter at a given proton fraction used as input in core-collapse supernova simulations. The phase transitions to the 2SC and CFL color superconducting phases lead to stable hybrid star configurations with a pure quark matter core.
