Density-driven correlations in many-electron ensembles: theory and application for excited states
Tim Gould, Stefano Pittalis
Density functional theory can be extended to excited states by means of a unified variational approach for passive state ensembles. This extension overcomes the restriction of the…

A shortcut to gradient-corrected magnon dispersion: exchange-only case
F. G. Eich, S. Pittalis, G. Vignale
Ab initio calculations of the magnon dispersion in ferromagnetic materials typically rely on the adiabatic local density approximation (ALDA) in which the effective exchange-correl…

Charge transfer excitations from exact and approximate ensemble Kohn-Sham theory
Tim Gould, Leeor Kronik, Stefano Pittalis
By studying the lowest excitations of an exactly solvable one-dimensional molecular model, we show that components of Kohn-Sham ensembles can be used to describe charge transfers.…
