Deconfinement phase transition under chemical equilibrium

Deconfinement Phase Transition in QCD

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...

When Is the Deconfinement Phase Transition Universal?

Pure Yang-Mills theory has a finite-temperature phase transition, separating the confined and deconfined bulk phases. Svetitsky and Yaffe conjectured that if this phase transition is of second order, it belongs to the universality class of transitions for particular scalar field theories in one lower dimension. We examine Yang-Mills theory with the symplectic gauge groups Sp(N). We find new evi...

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...

The Chiral and Deconfinement Phase Transition in QCD

The phase diagram of strongly interacting matter is one of the most exciting subjects of modern particle physics. While QCD lattice calculations become more and more realistic at vanishing chemical potential, their predictive power at finite chemical potential is still very limited due to the fermion sign problem. Until now lattice calculations cannot provide insights on the existence of a poss...
