High-precision two-dimensional atom localization via probe absorption in M-scheme atomic system

doi:10.1088/1674-1056/22/4/044203

Abstract In the present paper, we investigate the behavior of two-dimensional atom localization in a five-level M-scheme atomic system driven by two orthogonal standing-wave fields. We find that the precision and resolution of the atom localization depends on the probe field detuning significantly. And because of the effect of the microwave field, an atom can be located at a particular position via adjusting the system parameters.
