摘要

Two-dimensional (2D) atom localization via the spontaneously generated coherence (SGC) and detunings associated with the probe and standing-wave driving fields in a three-level V-type atomic system are investigated.In the gain process,two equal and tunable peak maxima of position distribution in the x-y plane via the detunings are observed.However,one decreasing and the other increasing peak maxima in the absorption process via the SGC are achieved in the quadrants Ⅰ and Ⅲ of the x-y plane.A better resolution and more novelty for the 2D atom localization in our scheme are obtained.
