Confinement of atoms with nondegenerate ground states in a three-dimensional dissipative optical superlattice

Based on the developed kinetic theory of rectified radiative forces, we found sufficient conditions for purely optical (nonmagnetic) three-dimensional confinement and cooling of atoms with the J=0 → J=1 quantum transition in a weak field of mutually orthogonal bichromatic standing waves. We show that a deep stable atom localization of atoms in the cells of an effective light superlattice (with a spacing much larger than the light wavelength) can be achieved by controlling the phase shifts (time-difference phase) of the temporal oscillations in orthogonally polarized field components and by specially choosing the field parameters. The proposed scheme of purely optical confinement can be directly used for a large group of atoms like Yb isotopes and alkali-earth elements with even-even nuclei.
