<title>Dynamic and thermodynamic properties of strongly anharmonic cubic crystals in the self-consistent phonon theory</title>

Abstract

On the basis of the reduced second-order self-consistent phonon approximation, based on the Green's functions method, the temperature and pressure variations of the dynamic and thermodynamic functions of strongly anharmonic crystals are computed and compared with experimental and other theoretical data. The system of self-consistent equations is solved for the generalized form of the Lennard-Jones (n,m) interatomic potential.
