Speaker 1: Dr. Pascal Krause (Institute of Chemistry, University Potsdam)
Title: Time-Dependent Configuration Interaction with an Absorbing Potential — Angle-dependent Ionization & High Harmonic Generation Spectra
Abstract: The strong field ionization has been studied for several molecules by time-dependent configuration interaction with an absorbing potential (TDCIS-CAP). The method employs an atom-centered basis set and can be applied to simulate electron dynamics and ionization in multi-electron polyatomic molecules. The presentation will address the calculation of angle-dependent ionization of small molecules as well as possibilities of simulating HHG spectra with TDCIS-CAP.

Title: Time-dependent two-particle reduced density matrix theory: Application to high-harmonic generation
Abstract: Calculating the dynamics of correlated quantum many-body systems is one of the great challenges of modern theoretical physics. Methods that have a polynomial scaling with particle number are required to address larger systems. We propose an efficient and accurate method based on the propagation of the two-particle reduced density matrix (TD-2RDM). We benchmark this approach by a comparison with multi-configurational time-dependent Hartree-Fock (MCTDHF) results for the harmonic spectra of Beryllium and Neon within a fully three-dimensional setup. We show that the TD-2RDM method is well-suited to describe the non-linear atomic response and to reveal the influence of electronic correlation effects.
