    Electronic Scattering Dynamics and Ultrafast Magnetization Dynamics

    A dynamical model for Elliott-Yafet type scattering of carriers and its importance for the demagnetization dynamics after ultrafast optical excitation is reviewed. It is pointed out that the demagnetization in...

    Electron Lifetimes in a 2D Electron-Gas with Rashba SO-Coupling: Screening Properties

    We calculate lifetimes due to electron-electron scattering in a 2D Rashba band structure and study the influence of the substrate screening. A comparison with measurements on the quantum-well system Bi/Cu(111)...

    Relaxation Dynamics of Majority and Minority Electrons After Ultrashort Laser Excitation

    We analyze the ultrafast demagnetization after ultrashort laser excitation by a kinetic model based on Elliott-Yafet scattering processes. By applying complete Boltzmann scattering integrals we trace the major...

    Optical absorption spectra of finite systems from a conserving Bethe-Salpeter equation approach

    We present a method for computing optical absorption spectra by means of a Bethe-Salpeter equation approach, which is based on a conserving linear response calculation for electron-hole coherences in the pres...

    Conserving quasiparticle calculations for small metal clusters

    A novel approach for GW-based calculations of quasiparticle properties for finite systems is presented, in which the screened interaction is obtained directly from a linear response calculation of the density-...
