Abstract
Recently, there have been several proposals for subwavelength atom localization based on the interaction of three-level atoms with light having space-dependent amplitude [1,2]. In all these proposals a spatially modulated dark state is created by means of either electromagnetically induced transparency (EIT) or coherent population trapping (CPT) [3]. Significant for the present work, the CPT technique with a Standing Wave (SW) control field produces atom localization in one of the ground states with a spatial fringe pattern resembling that of a Fabry-Perot resonator with cavity finesse given by the ratio R between the control and probe field intensities [2].
