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

TL;DR: A series of dimethine cyanine dyes were synthesized in a fast, efficient and high yield by the condensation of quaternary salts with lH-indole-3-carbaldehyde in the presence of piperidine under solvent-free microwave irradiation as mentioned in this paper.

TL;DR: In this paper, the dielectric response functions of crystalline ropes of metallic single-walled carbon nanotubes were determined from time-dependent density-functional theory in the random-phase approximation.

TL;DR: In this paper, a modified AMBER force field was used to compute the UV and NMR spectra of acetone in aqueous solution by an integrated computational tool rooted in the density functional theory, the polarizable continuum model, and classical molecular dynamics.

TL;DR: In this article, a combination of time-dependent density functional theory and the polarizable continuum model (PCM) is applied to study the ground-state geometries and the properties of electronic absorption spectra for some hemicyanine dyes with pyridine nucleus.

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.
