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 – 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.
