“…If the initial state of the medium is coherently prepared one can observe new effects: two resonant pulses may parametrically generate a third one [15]. The polariton description in the case of the tripod configuration, both in the classical and quantum versions, is similar to that for the Λ system but requires some modifications [16,17]. Two polaritons are necessary to describe the adiabatic evolution: they are now built of the electromagnetic component and two atomic excitations.…”

“…Three beams of light act on the atoms in a tripod configuration of the atom-light coupling [49][50][51][52][53][54][55][56][57][58][59][60]. Two strong classical control lasers induce transitions |2 → |0 and |3 → |0 , whereas a weaker probe field drives a transition |1 → |0 , as shown in Fig.…”

“…To avoid the losses we suggest to use an additional control laser without an optical vortex, so that the total intensity of the control lasers is non-zero at the vortex core of the first control laser. The probe and both control laser fields induce transitions between the atomic energy levels in a tripod configuration of the light-atom coupling [49][50][51][52][53][54][55][56][57][58][59][60] as depicted in Fig. 2a.…”

Polariton formalism is applied for studying the propagation of a probe field of light in a cloud of cold atoms influenced by two control laser beams of larger intensity. The laser beams couple resonantly three hyperfine atomic ground states to a common excited state thus forming a tripod configuration of the atomic energy levels involved. The first control beam can have an optical vortex with the intensity of the beam going to zero at the vortex core. The second control beam without a vortex ensures the loseless (adiabatic) propagation of the probe beam at a vortex core of the first control laser. We investigate the storage of the probe pulse into atomic coherences by switching off the control beams, as well as its subsequent retrieval by switching the control beams on. The optical vortex is transferred from the control to the probe fields during the storage or retrieval of the probe field. We analyze conditions for the vortex to be transferred efficiently to the regenerated probe beam and discuss possibilities of experimental implementation of the proposed scheme using atoms like rubidium or sodium.

“…On the other hand, slow light can be produced by non--EIT-based schemes [10]. Light propagation in terms of polaritons in a medium of atoms in the tripod configuration were discussed [11]. Controlling the group velocity of the light pulses has been recently studied [12].…”

One-dimensional propagation of ultraslow optical pulses in an atomic Bose-Einstein condensate taking into account the dispersion and the spatial inhomogeneity is investigated. Analytical and semi-analytical solutions of the dispersive inhomogeneous wave equation modeling the ultraslow pulse propagation are developed and compared against the standard wave equation solvers based upon Cranck-Nicholson and pseudo-spectral methods. The role of curvature of the trapping potential of the condensate on the amount of dispersion of the ultraslow pulse is pointed out.
