WebJul 5, 2013 · The basic principle of optical lattices relies on the optical dipole force: when neutral atoms are subjected to an ac electric field, this field dynamically induces a polarization into the atom. The induced dipole moment, in turn, interacts with the electric field and a force is exerted onto the atom.
