Two-Dimensional Atom Localization via Spontaneous Emission in an Inverted-Y System
Jianchun Wu, Zhengdong Liu, Jun Zheng, Huiqin Wang
Abstract
We investigate the behavior of two-dimensional atom localization in an inverted-Y system driven by one coherent field and two standing-wave fields. The position probability distribution of the atom passing through the spatial-position-dependent standing-wave fields can be determined by measuring the spontaneously emitted photon. It is found that high-precision two-dimensional atom localization can be obtained by choosing appropriate system parameters.
