Exploiting lattice potentials for sorting chiral particles
arXiv:1009.0650 · doi:10.1103/PhysRevLett.105.090602
Abstract
Several ways are demonstrated of how periodic potentials can be exploited for sorting molecules or other small objects which only differ by their chirality. With the help of a static bias force, the two chiral partners can be made to move along orthogonal directions. Time-periodic external forces even lead to motion into exactly opposite directions.
