The density gradient expansion of correlation functions
Robert van Leeuwen
We present a general scheme based on nonlinear response theory to calculate the expansion of correlation functions such as the pair-correlation function or the exchange-correlation…
Violation of the `Zero-Force Theorem' in the time-dependent Krieger-Li-Iafrate approximation
Michael Mundt, Stephan Kümmel, Robert van Leeuwen +1
We demonstrate that the time-dependent Krieger-Li-Iafrate approximation in combination with the exchange-only functional violates the `Zero-Force Theorem'. By analyzing the time-de…
Multicomponent Density-Functional Theory for Electrons and Nuclei
Thomas Kreibich, Robert van Leeuwen, E. K. U. Gross
We present a general multi-component density functional theory in which electrons and nuclei are treated completely quantum mechanically, without the use of a Born-Oppenheimer appr…
