Coherent control of three-dimensional atom localization based on different coupled mechanisms We present a new scheme for three-dimensional (3D) atom localization in a four-level atomic system based on different coupled mechanisms.

Abstract

We present a new scheme for three-dimensional (3D) atom localization in a four-level atomic system based on different coupled mechanisms. Owing to the space-dependent atom–field interaction, the position probability distribution of the atom can be directly determined by measuring the probe absorption and gain spectra. It is found that, based on different coupled mechanisms, the probability of finding the atom in 3D space is increased from 25% to 100%. Our scheme may be helpful in optical microscopy, the atom nano-lithography, and measurement of the center-of-mass wave function of moving atoms, etc.
