Deconfinement phase transition in compact stars: Maxwell versus Gibbs construction of the mixed phase

The Deconfinement Phase Transition in the Interior of Neutron Stars

The deconfinement phase transition which happens in the interior of neutron stars are investigated. Coupled with the spin evolution of the stars, the effect of entropy production and deconfinement heat generation during the deconfinement phase transition in the mixed phase of the neutron stars are discussed. The entropy production of deconfinement phase transition can be act as a signature of p...

The Deconfinement Phase Transition in Asymmetric Matter

We study the phase transition of asymmetric hadronic matter to a quarkgluon plasma within the framework of a simple two-phase model. The analysis is performed in a system with two conserved charges (baryon number and isospin) using the stability conditions on the free energy, the conservation laws and Gibbs’ criteria for phase equilibrium. The EOS is obtained in a separate description for the h...

Mapping the QCD Phase Transition with Accreting Compact Stars

We discuss an idea for how accreting millisecond pulsars could contribute to the understanding of the QCD phase transition in the high-density nuclear matter equation of state (EoS). It is based on two ingredients, the first one being a “phase diagram” of rapidly rotating compact star configurations in the plane of spin frequency and mass, determined with state-of-the-art hybrid equations of st...

Fluctuations near the Deconfinement Phase Transition Boundary

In this talk I discuss how a first order phase transition may proceed in rapidly expanding partonic matter produced in a relativistic heavy-ion collision. The resulting picture is that a strong collective flow of matter will lead to the fragmentation of a metastable phase into droplets. If the transition from quark-gluon plasma to hadron gas is of the first order, it will manifest itself by str...
