| Abstract: | We show that, by simple modifications of the usual three-level lambda-type scheme used in electromagnetically induced
transparency (EIT) schemes, phase dependence in the response of the atomic medium to a weak probe field can
be introduced. This gives rise to phase dependent susceptibility. By properly controlling phase and amplitudes
of the drive fields we obtain variety of interesting effects. On one hand we obtain phase control of the group
velocity of a probe field passing through medium to the extend that continuous tuning of the group velocity from
subluminal to superluminal and back is possible. While on the other hand, by choosing one of the drive fields to
be a standing wave field inside a cavity, we obtain sub-wavelength localization of moving atoms passing through
the cavity field. |
