Polarization induced by charged particles in real solids
I. Campillo, J. M. Pitarke
We report a first-principles description of the induced wake potential and density in real solids. The linear-response formalism is used to obtain the potential and density induced…
Band structure effects on the interaction of charged particles with solids
J. M. Pitarke, I. Campillo
A survey is presented of current investigations of the impact of band structure effects on various aspects of the interaction of charged particles with real solids. The role that i…
Hydrodynamic approximation for the nonlinear response of a metal surface
A. Bergara, J. M. Pitarke, R. H. Ritchie
We present semi-classical and quantized hydrodynamic models to obtain the quadratic electronic response of a plane-bounded electron gas. Explicit expressions for the dynamic image…
Self-energy of image states on copper surfaces
I. Sarria, J. Osma, E. V. Chulkov +2
We report extensive calculations of the imaginary part of the electron self-energy in the vicinity of the (100) and (111) surfaces of Cu. The quasiparticle self-energy is computed…
Inelastic lifetimes of hot electrons in real metals
I. Campillo, J. M. Pitarke, A. Rubio +2
We report a first-principles description of inelastic lifetimes of excited electrons in real Cu and Al, which we compute, within the GW approximation of many-body theory, from the…
Plasmonic excitations in noble metals: The case of Ag
M. A. Cazalilla, J. S. Dolado, A. Rubio +1
The delicate interplay between plasmonic excitations and interband transitions in noble metals is described by means of {\it ab initio} calculations and a simple model in which the…
