    "abstract": "We show that, by simple modifications of the usual three-level $\\Lambda$-type\nscheme used for obtaining electromagnetically induced transparency (EIT), phase\ndependence in the response of the atomic medium to a weak probe field can be\nintroduced. This gives rise to phase dependent susceptibility. By properly\ncontrolling phase and amplitudes of the drive fields we obtain variety of\ninteresting effects. On one hand we obtain phase control of the group velocity\nof a probe field passing through medium to the extent that continuous tuning of\nthe group velocity from subluminal to superluminal and back is possible. While\non the other hand, by choosing one of the drive fields to be a standing wave\nfield inside a cavity, we obtain sub-wavelength localization of moving atoms\npassing through the cavity field.",
