We construct the expansion of a Bloch wave with energy E into a complete set of multipole waves around a "center" of a crystal as an analog of the expansion in spherical waves in free space. Crystal point group symmetry is used to classify the set. The density of states in a cell is then analyzed into multipole components whose magnitude depends on the cell's distance from the "center."

Abstract
We construct the expansion of a Bloch wave with energy E into a complete set of multipole waves around a "center" of a crystal as an analog of the expansion in spherical waves in free space. Crystal point group symmetry is used to classify the set. The density of states in a cell is then analyzed into multipole components whose magnitude depends on the cell's distance from the "center."File in questo prodotto:
