Ultrafast electron dynamics in metals
J. M. Pitarke, V. P. Zhukov, R. Keyling +2
During the last decade, significant progress has been achieved in the rapidly growing field of the dynamics of {\it hot} carriers in metals. Here we present an overview of the rece…
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…
Surface effects on the electronic energy loss of charged particles entering a metal surface
A. Garcia-Lekue, J. M. Pitarke
Surface effects on the electronic energy loss of charged particles entering a metal surface are investigated within linear-response theory, in the framework of time-dependent densi…
Image-potential-induced states at metal surfaces
P. M. Echenique, J. M. Pitarke, E. V. Chulkov +1
The unequivocal observation in the early 1980s of a new class of unnocupied surface states that are bound to the vacuum level of a variety of metal surfaces has led over the last t…
An inhomogeneous and anisotropic Jastrow function for non-uniform many-electron systems
A. Garcia-Lekue, M. Nekovee, J. M. Pitarke +1
Quantum Monte Carlo simulations of interacting electrons in solids often use Slater-Jastrow trial wave functions. The Jastrow function takes into account correlations between pairs…
Dynamic structure factor of gold
I. G. Gurtubay, J. M. Pitarke, I. Campillo +1
We have investigated the role of localized {\it d} bands in the dynamical response of Au, on the basis of {\it ab initio} pseudopotential calculations. The density-response functio…
