β¦ Synopsis
The equivalent neighbour (EN) model of interacting continuous spherically symmetric spins with the length equal or smaller than unity is solved exactly for all values of the spin dimensionality, D. A surprising result is that only for D > 8 the system undergoes phase transitions at temperatures lower than those of the EN model of interacting spins with the hypercubic symmetry. In the D+ m limit the equation of state in zero field is derived analytically and gives the Landau type behaviour in the whole range of temperatures.

Principles of statistical physics are applied for the description of thermodynamic equilibrium in disperse systems. The cells of disperse systems are shown to possess a number of non-standard thermodynamic parameters. A random distribution of these parameters in the system is determined. On the basi
We investigate the probability distribution of the quantum fluctuations of thermodynamic functions of finite, ballistic, phase-coherent Fermi gases. Depending on the chaotic or integrable nature of the underlying classical dynamics, on the thermodynamic function considered, and on temperature, we fi
The corresponding states theory for liquids consisting of polysegmented molecules is extended to mixtures of paraff-mic, olefinic, naphthenic and aromatic hydrocarbons; the previously derived partition function is generalized to yield expressions for the excess free energy, enthalpy and entropy. It
