摘要

We show that it is possible to spatially separate a ("racemic") mixture of left-handed andright-handed chiral molecules using optically induced forces. The separation is affected by theirradiation of the racemic mixture with three spatially inhomogeneous and partially overlapping cwlaser fields, giving rise to enantiomeric and vibrational dependent light-induced forces. Twoexperimental arrangements, one consisting of placing the racemate in 1 mK optical trap, the secondcomposed of a tightly skimmed molecular beam of the racemic mixture, forming one arm of afour-sided cavity, are numerically tested by performing quantum wave packet propagation andclassical trajectories. Both the classical and the quantum simulations show an essentially perfectspatial separation between enantiomers of several vibrational states.
