Quark matter produced in relativistic nuclear collisions is thermally equilibrated. A phenomenological model is used to calculate the yield of strange quark pairs at AGS, SPS and RHIC, which is comparable to the results from the experiments. In addition, analysis with this model indicates that there is a signal of phase transition where the cms energy is approximately 7.5 GeV.

The Mean

Tilt angle (order parameter) and the susceptibility are calculated as a function of temperature for the [Formula: see text]–[Formula: see text] transition in quartz using a Landau phenomenological model. The tilt angle as obtained from the model is fitted to the experimental data from the literature and the temperature dependence of the tilt angle susceptibility is predicted close to the [Formula: see text]–[Formula: see text] transition in quartz. Our results show that the mean field model explains the observed behavior of the [Formula: see text]–[Formula: see text] phase transition in quartz adequately and it can be applied to some related materials.

Superfluid Fermi

Soft transitional nuclei are considered in a model of a finite superfluid Fermi system in the vicinity of a phase transition. Microscopic estimates are given for the limiting strength of anharmonicity in such a system. The estimates are based on collectivity, adiabaticity and quadrupole symmetry of large amplitude collective motion. The results imply the leading role of quartic anharmonicity and the O(5) dynamical symmetry of low-lying spectra. It justifies the phenomenological model suggested earlier which turned out to be quite successful in description of data.
