The lattice dynamics of the model is treated in the self-consistent phonon approximation. The free energy is found to show the behaviour characteristic of a second-order phase transition, but the temperature of the transition is not the same as the temperature at which the frequency of the ...

We also studied two simpler self-consistent phonon approximations, the self-consistent Einstein and Debye approximations, and report their zero- and high-temperature predictions. 展开 DOI: 10.1103/PhysRevB.23.2782 被引量: 12 年份: 1981 收藏 引用 批量引用 报错 分享 ...
The dynamic form factor, S(Q⃗, ω), of fcc 4He at high density is calculated, including the one-phonon, the two-phonon, and interference contributions, for comparison with the recent neutron-scattering measurements of Eckert et al. and of Thomlinson et al. The purpose is to test how ...
The thermodynamic properties of solid Ar, Kr and Xe are investigated within the framework of the self-consistent phonon method. We have used a central two-body potential of the MieLennard-Jones type. The lowest order self-consistent scheme, the so-called self-consistent phonon harmonic ...
In particular, we examine the self-consistent phonon approximation with an intercell coupling which possesses a variable range of interaction. In the limit where the interaction is of sufficiently long range, the density matrix of the system is obtained numerically exactly.doi:10.1080/00150197408238055...
The second order contribution to the free energy from four-phonon processes is calculated according to a perturbative approach based on the self-consistent phonon formalism. The results are compared with experiment. A technique for substantially reducing computer time requirements for multiple scans over...
The self‐consistent phonon approximation of anharmonic lattice dynamics is applied to solid β nitrogen. Completely disordered molecular orientations and a Lennard‐Jones 6–12 intermolecular potential are assumed. The quantities calculated are the phonon spectrum and the thermal expansion as a function...
Intermediate lines in the self-energy are described self-consistently, thereby including multiple-phonon core excitations. It is shown that the equation for the self-energy may be solved by matrix diagonalization by coupling the even- and odd-nuclear eigenmodes. Renormalized phonons are calculated ...
