Influence of laser properties on the high-order harmonic generation process in benzene — •Samuel Schöpa and Dieter Bauer — Institute of Physics, University of Rostock, Rostock, Germany

We solve the Schrödinger equation for benzene by expanding the wave function in a linear combination of ground-state Kohn-Sham orbitals. Those have been calculated previously via ground-state density functional theory. This method is orders of magnitude faster than comparable full time-dependent density functional theory simulations but neglects the update of the Hartree-exchange-correlation potential during time evolution. The selection rules stemming from the 6-fold symmetry of the benzene molecule as well as the opposite polarization of each harmonic couple are observed for a laser field at normal incidence that is circularly polarized in the molecular plane. We investigate how ellipticity and angle of incidence of the laser influence the spectrum. The selection rules are broken already for small deviations from normal incidence.
