Local density-functional theory of frequency-dependent linear response.

TL;DR: The plasmon-resonance line shape for k\ensuremath{\rightarrow}0 and the plAsmon dispersion curves including local-field effects and exchange-correlation corrections are calculated and compared with both empirical and experimental data.

TL;DR: The spin-wave dynamics of a magnetic material is derived from the time-dependent spin-density-functional theory in the linear response regime and a gradient expansion scheme based on the homogeneous spin-polarized electron gas is proposed.

TL;DR: This work examines the constrained density functional theory-configuration interaction method for use in computing electronic excited states, for the challenging case of conical intersections, and suggests that with a suitable definition of atomic populations and a careful choice of constrained states, it could be the basis for a seamless description of electronic degeneracy.

TL;DR: The well-known single-pole approximation for excitation energies is derived here in an alternative way and extended to time-dependent current-density-functional theory.

TL;DR: In this article, the ground state of an interacting electron gas in an external potential was investigated and it was proved that there exists a universal functional of the density, called F[n(mathrm{r})], independent of the potential of the electron gas.

TL;DR: In this article, a time-dependent version of density functional theory was proposed to deal with the non-perturbative quantum mechanical description of interacting many-body systems moving in a very strong timedependent external field.

TL;DR: Theoretical predictions on the dynamic properties are compared with the x ray and electron scattering data for the metallic electrons as discussed by the authors, and screening effects are analyzed and applied to calculations of the enhancement factor of the thermonuclear reaction rate and the electric resistivity in dense plasmas.

TL;DR: In this article, a density-functional theory for describing polarization-type many-body effects influencing the photoresponse of small electronic systems is presented. But it does not take account of the time-dependent fields induced by an external radiation field.
