Abstract

A new optomechanical chiral resolution scheme for molecules possessing a permanent dipole moment is proposed. The approach involves the following molecular manipulation sequence: (i) a molecular alignment electromagnetic pulse, (ii) a time-delayed dipole orienting static electric field, and (iii) scattering from a frictional surface. The method offers various control parameters including pulse duration and intensity, static field strength, delay time, surface dynamic friction coefficient, and incident molecular velocity that can be tuned to optimize spatial enantioseparation. The scheme is demonstrated for the prototypical HSOH chiral molecule, predicting an enantiomeric excess as high as 50%.
