Exact Dynamically Convergent Calculations of the Frequency-Dependent Density Response Function.

Abstract

A general expression for the response function is derived by the method of recurrence relations. Memory effects appear as corrections to the dynamic RPA form. The dynamic structure for the 3d electron gas is calculated to third order and compared with Al data as a large wave vector. Also shown is the dynamic local-field term. (Author)
