Investigation of the Thermodynamic Properties of Anharmonic Crystals with Defects by the Moment Method

Abstract

By the moment method established previously on the basis of the statistical mechanics, the thermodynamic properties of a strongly anharmonic face-centered and body-centered cubic crystal with point defect are considered. The thermal expansion coefficient, the specific heat C_v and C_p, the isothermal and adiabatic compressibility, etc. are calculated.
