Measuring discriminatory optical forces on chiral molecules — •Tianyu Fang, Nick Vogeley, Kilian Singer, and Daqing Wang — Institute of Physics, University of Kassel, Heinrich-Plett-Straße 40, 34132 Kassel, Germany

We aim at a proof-of-principle experimental demonstration of enantiomer separation using optical forces created by a spatially tailored optical field. Chiral molecules with opposite handedness scatter polarized light differently. Consequently, the scattering of a photon exerts a force on the scatterer. This force can be tailored to be enantiomer specific, such that molecules of opposite handedness are pushed to opposite directions. In this poster, we outline an experiment, in which such discriminatory forces will spatially separate enantiomers in a propagating molecular beam.
