- W2017474179 abstract "A theory of multiphonon absorption due to anharmonicity in crystals is presented, employing a Green's-function technique. In contrast to previous theories, we do not expand the lattice-interaction potential in powers of displacements. We are therefore able to obtain a single expression for the absorption coefficient $ensuremath{alpha}$, which includes various classes of contributions to infinite order in phonons, and which is valid for all frequencies in the multiphonon regime. The results involve just the displacement-correlation tensor of the lattice, and the Fourier components of the interatomic potential $ensuremath{nu}$. Simplified expressions are obtained for isotropic models, and specific choices of $ensuremath{nu}$. Within the Einstein model, one finds an exponential behavior, $ensuremath{alpha}(ensuremath{omega})ensuremath{sim}{e}^{ensuremath{-}ensuremath{sigma}ensuremath{omega}}$; predicted values of $ensuremath{sigma}$ within the model are found to be in good agreement with recent experimental data on alkali halides. A general technique for evaluating $ensuremath{sigma}$, the method of convolutions, is elaborated. Predictions regarding the frequency and temperature dependence of $ensuremath{sigma}$ are discussed and compared with other work." @default.
