Spatial Distribution of Atoms in the Field of Intersecting Standing Bichromatic Light Waves

Abstract

We have shown that, by properly detuning the carrier frequencies in each of two perpendicularly intersecting bichromatic waves from the atomic transition frequency, it is possible to create a two-dimensional trap for atoms, if the wave intensities are sufficiently high. At the zero and near-zero values of the initial wave phases, as well as at the phase shift between the intersecting waves equal to п or close to п values, the dynamic spatial patterns of atoms consisting of square cells with the side length equal to л/√2 are formed. Numerical simulations were carried out for sodium atoms.
