Deconfinement at finite baryon number density

Unifying Nucleon and Quark Dynamics at Finite Baryon Number Density

We present a model of baryonic matter which contains free constituent quarks in addition to bound constituent quarks in nucleons. In addition to the common linear σ-model we include the exchange of vector-mesons. The percentage of free quarks increases with baryon density but the nucleons resist a restoration of chiral symmetry.

Deconfinement and Non–zero Baryon Density

Substantial progress has been achieved in the understanding of the phase diagram of models that share the same global symmetries of QCD . Confinement, however, is not handled in a completely satisfactory way by these studies. Among the approaches which include confinement, the monomer– dimer–polymer representation of the partition function 2 is limited to the infinite gauge coupling limit, wher...

Strongly Coupled QCD at Finite Baryon Density

Finite Density QCD is affected by the well known sign problem that has prevented, in most cases, any success in simulate this theory and, until now, no solution is at sight. The only exceptions in this scenario are strong coupling simulations performed with the Monomer Dimer Polymer (MDP) algorithm [1]. This algorithm is able to provide results not affected by early onset and in partial agreeme...

Deconfinement at finite chemical potential

In a confining, renormalisable, Dyson-Schwinger equation model of two-flavour QCD we explore the chemical-potential dependence of the dressed-quark propagator, which provides a means of determining the behaviour of the chiral and deconfinement order parameters, and low-energy pion observables. We find coincident, first order deconfinement and chiral symmetry restoration transitions at μc = 375M...
