Linear response approach to collective electronic excitations of solids and surfaces
Description
Abstract We have developed a parallel computer program for the study of dynamic response of periodic systems. It computes the linear response of an interacting many-electron system from its ground-state electronic structures, which are obtained from ab initio band structure calculations in the plane-wave and pseudopotential scheme. As test examples, we applied this program to calculate the linear response of bulk aluminum and a beryllium monolayer. The excitation spectra show prominent plasmon resonan... Title of program: Dresponse Catalogue Id: AECK_v1_0 Nature of problem The dynamic response of bulk and surface systems. It is usually dominated by collective electronic excitations (plasmons) at low-energy range.
