Plasmon Lifetime in K: A Case Study of Correlated Electrons in Solids Amenable to Ab Initio Theory

Wei Ku, Adolfo G. Eguiluz

On the basis of a new ab initio, all-electron response scheme, formulated within time-dependent density-functional theory, we solve the puzzle posed by the anomalous dispersion of…

Dynamical Response of Correlated Electrons in Solids Probed by Inelastic Scattering Experiments: An Ab Initio Theoretical Perspective

Adolfo G. Eguiluz, Wei Ku, James M. Sullivan

We present results of ab initio theoretical investigations of the excitation spectra of correlated electrons in metals (Al, K, and Li) and their interplay with inelastic scattering…

Ab Initio Evaluation of Plasmon Lifetimes in the Alkali Metals

Wei Ku, Adolfo G. Eguiluz

The anomalous plasmon linewidth dispersion (PLD) measured in K by vom Felde, Sprosser-Prou, and Fink (Phys. Rev. B 40, 10181 (1989)), has been attributed to strong dynamical electr…

Electronic stopping power of aluminum crystal

I. Campillo, J. M. Pitarke, A. G. Eguiluz

Ab initio calculations of the electronic energy loss of ions moving in aluminum crystal are presented, within linear-response theory, from a realistic description of the one-electr…

Theory of the "honeycomb chain-channel" reconstruction of Si(111)3x1

Steven C. Erwin, Hanno H. Weitering

First-principles electronic-structure methods are used to study a structural model for Ag/Si(111)3x1 recently proposed on the basis of transmission electron diffraction data. The f…

Low temperature resistivity in a nearly half-metallic ferromagnet

Xindong Wang, X. -G. Zhang

We consider electron transport in a nearly half-metallic ferromagnet, in which the minority spin electrons close to the band edge at the Fermi energy are Anderson-localized due to…
