Effects of the crystal structure in the dynamical electron density-response of hcp transition metals
I. G. Gurtubay, Wei Ku, J. M. Pitarke +1
We present an all-electron study of the dynamical density-response function of hexagonal close-packed transition metals Sc and Ti. We elucidate various aspects of the interplay bet…
AB Initio Studies of Electronic Excitations in Real Solids
Adolfo G. Eguiluz, Wei Ku
The first part of this article centers on the fact that key features of the dynamical response of weakly-correlated materials (the alkalis, Al), have been found experimentally to d…
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…
Electronic Excitations and Correlation Effects in Metals
Adolfo G. Eguiluz, Wolf-Dieter Schoene
Theoretical descriptions of the spectrum of electronic excitations in real metals have not yet reached a fully predictive, "first-principles" stage. In this paper we begin by prese…
