PNJL model at zero temperature: The three-flavor case

Phenomenology of the three-flavor PNJL model and thermal strange quark production

We study the temperature dependence of the adjoint Polyakov loop and its implication for the momentum spectrum of gluons in the mean-field approximation. This allows us to calculate the contribution of the thermal (transverse) gluons to the thermodynamic pressure. As an application, we evaluate the rates for the strange quark pair-production processes q ¯ q → s¯ s and gg → s¯ s as functions of ...

Zero-temperature freezing in the three-dimensional kinetic Ising model.

We investigate the relaxation of the Ising-Glauber model on a periodic cubic lattice after a quench to zero temperature. In contrast to the conventional picture from phase-ordering kinetics, we find the following: (i) domains at long time are highly interpenetrating and topologically complex, with average genus growing algebraically with system size; (ii) the long-time state is almost never sta...

Thermodynamics of the PNJL model

QCD thermodynamics is investigated by means of the Polyakov-loop-extended Nambu Jona-Lasinio (PNJL) model, in which quarks couple simultaneously to the chiral condensate and to a background temporal gauge field representing Polyakov loop dynamics. The behaviour of the Polyakov loop as a function of temperature is obtained by minimizing the thermodynamic potential of the system. A Taylor series ...

Numerical study of the three-dimensional random-field Ising model at zero and positive temperature

The Four-fermi Model in Three Dimensions at Non-zero Density and Temperature

The Four Fermi model with discrete chiral symmetry is studied in three dimensions at nonzero chemical potential and temperature using the Hybrid Monte Carlo algorithm. The number of fermion flavors is chosen large (Nf = 12) to compare with analytic results. A first order chiral symmetry restoring transition is found at zero temperature with a critical chemical potential μc in good agreement wit...
