title: Spatial separation of dimers of chiral molecules.
abstract: A method for the spatial separation of R-R and S-S homodimers from R-S heterodimers, where R and S are chiral molecules of opposite handedness ("enantiomers"), is introduced. The separation, achieved by using two spatially inhomogeneous time-delayed laser pulses, is a result of one type of dimer forming a "dark state" and experiencing no light-induced potential, while the other type of dimer, forming a "bright" state, undergoes deflection. The direction of deflection of the two types of chiral dimers may be reversed by reversing the time delay between the laser pulses. We demonstrate the feasibility of the process by simulating the separation of lactic acid dimers.
