The anomalous behavior of the thermodynamic co-ordinates along with the hadronic critical temperature (Tc) is studied and the properties of the surrounding vacuum are investigated in the framework of the Ginzburg-Landau theory of superconductivity, with interesting conclusions.

In this paper, we have investigated the presence of multifractality and the possibility of quark–hadron phase transition in the multiparticle production in [Formula: see text]O–AgBr, [Formula: see text]Si–AgBr and [Formula: see text]S–AgBr interactions at 4.5[Formula: see text]AGeV/[Formula: see text] in the framework of Ginzburg–Landau theory of second-order phase transition following the Takagi moment methodology. The same analysis with the factorial moment method has also been performed. Experimental results have been compared with the prediction of UrQMD and AMPT models. A comparison of experimental results with the analysis of UrQMD simulated RHIC data by the method of Takagi moment has also been presented. Comparison of experimental results with previous results of emulsion experiments has been mentioned.

A logarithmic behavior is hidden in the linear temperature regime of the electrical resistivity R(T) of some YBCO sample below 2T c where "pairs" break apart, fluctuations occur and "a gap is opening". An anomalous effect also occurs near 200 K in the normal state Hall coefficient. In a simulation of oxygen diffusion in planar 123 YBCO, an anomalous behavior is found in the oxygen-vacancy motion near such a temperature. We claim that the behavior of the specific heat above and near the critical temperature should be reexamined in order to show the influence and implications of fluctuations and dimensionality on the nature of the phase transition and on the true onset temperature.
