スポンサーリンク
概要
- 論文の詳細を見る
A unified dynamical theory of quantum solids is formulated in the self-consistent reaction matrix approach. The phonon dispersion relation is derived in a determinantal form by linearizing the coupled equation of motion for operators bilinear in creation and annihilation operators of localized single-particle states. Comparison with the traditional lattice dynamics is given.
