Role of electron-phonon interactions versus electron-electron interactions in the broadening mechanism of the electron and hole linewidths in bulk Be (2005)

Sklyadneva,Irina Yu., Chulkov,Eugene V., Schöne,Wolf-Dieter, Silkin,Viatcheslav M., Keyling,Robert, Echenique,Pedro M.

We report on ab initio study of electron-phonon (e-ph) and electron-electron (e-e) interactions in bulk Be. The calculations show that the e-ph coupling parameter lambda varies from 0.01 to 1.02 as a...

Role of spin in quasiparticle interference (2004)

Pascual,Jose I., Bihlmayer,Gustav, Koroteev,Yu. M., Rust,Hans-Peter, Ceballos,Gustavo, Hansmann,Martin, ...

Quasiparticle interference patterns measured by scanning tunneling microscopy can be used to study the local electronic structure of metal surfaces and high-temperature superconductors. Here, we show...

Anomalous Quasiparticle Lifetime in Graphite: Band Structure Effects (2001)

Spataru, Catalin D., Cazalilla, Miguel A., Rubio, Angel, Benedict, Lorin X., Echenique, Pedro M., Louie, Steven G.

We report ab initio calculation of quasiparticle lifetimes in graphite, as determined from the imaginary part of the self-energy operator within the GW aproximation. The inverse lifetime in the...

Semiclassical image potential at a solid surface (1981)

Echenique, Pedro M., Ritchie, R. H., Barberán Falcón, Núria, Inkson, John C.

A surface dielectric function of a semi-infinite plane-bounded metal is defined in the spirit of the plasmon-pole dielectric function of the bulk. It is modeled in such a way that the surface-plasmon...

Comment on the plasmon model for image-potential-induced surface states (1979)

Barberán Falcón, Núria, Echenique, Pedro M.

Calculations of the binding energy of bound positron states in metal surfaces, with explicit inclusion of plasmon dispersion and single-particle effects, are presented. The binding energy is greatly...
