Circular dichroism in photoionization of chiral systems by intense laser pulses — •Anton N Artemyev¹, Anne D Müller¹, David Hochstuhl², and Philipp V Demekhin¹ — ¹Institut für Physik, Universität Kassel, Heinrich-Plett-Str. 40, 34132 Kassel — ²Institut für Theoretische Physik und Astrophysik, 24098 Kiel

It is well known that chiral molecules interact in different ways with left and right circular polarized light. This phenomenon is known as circular dichroism. Here, we systematically investigate circular dichroism in the angular-resolved photoionization and above threshold ionization spectra of model chiral systems. To this end, we numerically solve the time-dependent Schrödinger equation for the single-active-electron wave-packet in a chiral pseudo-potential in the presence of intense circularly polarized laser pulses. The results, obtained in different model potentials for fixed-in-space and randomly oriented systems, are reported.
