Time-resolved exciton wave functions from time-dependent density-functional theory
Jared R. Williams, Nicolas Tancogne-Dejean, Carsten A. Ullrich
Time-dependent density-functional theory (TDDFT) is a computationally efficient first-principles approach for calculating optical spectra in insulators and semiconductors, includin…

A reformulation of time-dependent Kohn-Sham theory in terms of the second time derivative of the density
Walter Tarantino, Carsten A. Ullrich
The Kohn-Sham approach to time-dependent density-functional theory (TDDFT) can be formulated, in principle exactly, by invoking the force-balance equation for the density, which le…

Optical properties of CsCuX (X=Cl, Br and I): A comparative study between hybrid time-dependent density-functional theory and the Bethe-Salpeter equation
Jiuyu Sun, Carsten A. Ullrich
The cesium copper halides CsCuX (X=Cl, Br and I) are a class of all-inorganic perovskites with interesting and potentially useful optical properties, characterized by disti…
