    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-...
