Generalized time-dependent density-functional theory including core polarization

A generalization of the time-dependent density-functional-theory for metal clusters which treats both valence and core polarization on the same microscopic basis is presented. The self-consistency between valence and core responses is taken into account by means of a modified kernel and external field in the linearized response equations. the general case of an arbitrary external field and cluster structure, with given specific atomic positions, is presented.
