A self-consistent statistical method for the calculation of thermodynamic properties for simple crystals is used to study the formation of vacancies in rare gas crystals (RGC) at high temperature near the melting point. We show that the vacancy forma

The thermal properties of the simple fcc metals Cu and Ag are investigated within a self-consistent statistical approach. The method is based on a variation procedure calculating a parameter of the quasi-elastic bond of neighboring atoms. The effecti

A theory of a one-dimensional quantum crystal with the Morse potential of the interatomic interaction is proposed. Analytic expressions for equilibrium crystal parameters at various pressures are found. We show the possibility of a type of delocalize

The self-consistent quasiharmonic model is used to describe the equilibrium atomic structure of a crystal and the thermodynamical properties of vacancies at high temperature. It is shown that an increase in the amplitude of the thermal atomic vibrati

A self-consistent statistical method [Phys. Rev. B 66, 054302 (2002)] is used to describe the thermodynamic properties of free rare gas nanocrystals, using thin plates as examples. It is shown that the influence of size on the thermodynamic propertie

We demonstrate that the discrete character of the vibrational spectrum of a small crystal accounts for size dependence of its thermodynamic properties and melting temperature. Using a self-consistent statistical method [Phys. Rev.B 66, 054302 (2002)]

A self-consistent statistical method is used to calculate the Gibbs free energy of vacancy formation in heavy rare gas crystals at high temperature. It is shown that the vacancy formation free energy falls rapidly in the vicinity of the melting point

We propose a method of statistical description of simple crystals and calculation of their thermodynamic functions and equation of state. The method is based on the derivation of an exact expression for the binary distribution function of atomic disp
