The European Physical Journal A, 2007 Results are presented from a numerical study of lattice QCD with gauge group SU(2) and two flavors of Wilson fermion at non-zero quark chemical potential mu >> T. Studies of the equation of state, the superfluid condensate, and the Polyakov line all suggest that in addition to the low density phase of Bose-condensed diquark baryons, there is a ...

NEUTRON MATTER – QUARK MATTER PHASE TRANSITION AND QUARK STAR [PDF]
International Journal of Modern Physics E, 1993 We consider the neutron matter and 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. The quark matter sector is treated perturbatively

Quark Matter May Not Be Strange [PDF]
Physical Review Letters, 2018 If quark matter is energetically favored over nuclear matter at zero temperature and pressure then it has long been expected to take the form of strange quark matter (SQM), with comparable amounts of $u$, $d$, $s$ quarks. The possibility of quark matter with only $u$, $d$ quarks ($ud$QM) is usually dismissed because of the observed stability of ...

Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]
, 2012 We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

Enhancement of baryon-to-meson ratios around jets as a signature of medium response
Physics Letters B, 2023 We present a unique signal of jet-induced medium excitations: the enhancement of baryon-to-meson ratios around the quenched jets. To illustrate this, we study jet-particle correlations and the distributions of jet-induced identified particles with ...

Scaling and adiabaticity in a rapidly expanding gluon plasma
Journal of High Energy Physics, 2022 In this work we aim to gain qualitative insight on the far-from-equilibrium behavior of the gluon plasma produced in the early stages of a heavy-ion collision.

Quark star matter in heavy quark stars
European Physical Journal C: Particles and Fields, 2021 We study the thermodynamic properties of asymmetric quark matter and large mass quark stars within the confined-isospin-density-dependent-quark-mass model. We find that the quark matter symmetry energy should be very large in order to describe the recent

Chiral magnetic effect and three-point function from AdS/CFT correspondence
Journal of High Energy Physics, 2021 The chiral magnetic effect with a fluctuating chiral imbalance is more realistic in the evolution of quark-gluon plasma, which reflects the random gluonic topological transition.

QUARK MATTER SYMMETRY ENERGY AND QUARK STARS [PDF]
The Astrophysical Journal, 2013 We extend the confined-density-dependent-mass (CDDM) model to include isospin dependence of the equivalent quark mass. Within the confined-isospin-density-dependent-mass (CIDDM) model, we study the quark matter symmetry energy, the stability of strange quark matter, and the properties of quark stars.
