This project aims at developing a numerical model system describing a chiral potential environment for an electron. Interaction of this system with intense, circularly polarized laser fields leads to ionization, i.e. emission of the electron. The asymmetric angular distribution of the electron (multiphoton-photoelectron circular dichroism, PECD) will be numerically calculated. This simple model does not provide information on multi-electron effects, however, the role of intermediate, excited states and the continuum, which are not properly described in existing approaches, can be well examined. The results of the quantum dynamical calculations of this model system will be compared to existing approaches calculating PECD. The focus lies on the examination of the interaction of chiral systems with intense, ultrashort laser pulses with only a few optical cycles. Such pulses inherently possess a strong asymmetry. We intend to investigate if and how this additional asymmetry of the laser pulse may lead to a modification of the (asymmetric) angular distribution of photoelectrons.We plan to closely collaborate with the group of Prof. Dr. Matthias Wollenhaupt (Universität Oldenburg) who experimentally aim at investigating PECD for intense, few-cycle laser pulses.
