Rotational effects on enantioseparation — •Andreas Jacob and Klaus Hornberger — Universität Duisburg-Essen, Fakultät für Physik, Lotharstraße 1-21, 47057 Duisburg

Recently, several ideas to separate enantiomers have been proposed, i.e. to split molecules in a left handed configuration from their right handed mirror state [1,2]. They are based on the dynamics caused by the equations of motion in an adiabatic basis produced by laser induced gauge potentials. Since the effect of molecular rotation has been neglected in these studies, we study the influence of the orientation state on the enantioseparation by numerical integration of the full molecular rotation state. We find that the potential from the adiabatic dressed state approach cannot be recovered, even in the rotational ground state. The obtained time-averaged interaction potentials and the associated forces are then strongly diminished, but they can still exhibit chiral sensitivity.
