Theory of laser-driven many electron dynamics: Simulations for metallic model systems and small molecules — •Tillmann Klamroth, Pascal Krause, and Christian Huber — Universität Potsdam, Institut für Chemie, Theoretische Chemie, Karl-Liebknecht-Str 24-25, D-14476 Potsdam, Germany

We report simulations of laser-driven many electron dynamics by means of time-dependent configuration interaction methods, namely the configuration interaction singles method (CIS) and the CIS(D) method, in which doubly excited configuration are included perturbatively. These methods are many-electron approaches in which electron-electron-scattering is approximately accounted for.

We present applications to one-dimensional metallic model systems for simulations of laser-driven charge transfer in metal-insulator-metal contacts and of 2-photon-photoelectron-spectra for small metal slabs. The CIS(D) method is used to simulate electron dynamics of small (three-dimensional) molecules in intense laser fields.
