“…This was observed in various experimental configurations including those of early experimental as well as theoretical considerations described in [1][2][3][4][5][6][7]. EIT effects have been observed in three basic configurations containing three discrete atomic levels, namely Λ-, V -type and ladder configa e-mail: caolongvanuz@gmail.com urations (for the ladder system [8] and Λ-model [9,10], sometimes extended Lambda-models involving more than two lower levels are referred to as "tripod" ones [11,12]). …”

Abstract.A Λ-like model of atomic levels involving two auto-ionizing states is considered. The levels are irradiated by two external electromagnetic fields, a strong driving and a weak probing ones. The analytical formula for medium susceptibility shows an additional electromagnetically induced transparency window caused by the second auto-ionizing level. Characteristics of both transparency windows are analyzed depending on parameters of auto-ionizing levels and the external driving field. Manipulation of these characteristics seems to be very effective because of their large sensitivity with respect to the parameters involved in the problem. This manipulation becomes even more feasible when considered model is implemented in so-called laser-induced continuum structure.

“…This concerns both their positions with respect to Δ p = 63 MHz and the corresponding heights. For better understanding of these points, we refer the reader to our five-level calculations with the other parameter values chosen [21,22], the appropriate four-level calculations, our calculations with the state |3> neglected [21,22], and those performed in Ref. [23], which have been related to D1 line of 133 Cs.…”

Abstract. We calculate electric susceptibility of a laser-dressed atomic medium. The model adopted in this work refers to the experiment with cold 85 Rb atoms, where the states F′ = 1, 2, 3 of the hyperfine manifold 5P 3/2 (F′) are strongly coupled with the ground state 5S 1/2 (F = 2), and the coupling is probed by a weak probing field from the other ground-state component 5S 1/2 (F = 3). We present a five-level model in which the states F = 2, 3 and F′ = 1, 2, 3 are taken into account, while the noncoupled state F′ = 4 is neglected. The model is used as a starting point to reproduce spectral features observed in the absorption of probe light passing through a cold sample of 85 Rb atoms in a magneto-optical trap. Basing on numerical solutions of this model, we have also studied in detail the impact on the probe spectra from the presence of the state F′ = 1 to which probing is forbidden by electric-dipole transition, but coupling is allowed [see, e.g., Proc. of SPIE 8770 (2013)

“…Electromagnetically induced transparency (EIT) phenomenon relies on the destructive quantum interference of the transition amplitudes involved in the system that leads to the suppressing of the absorption or even the complete transmission of the resonant weak probe beam in the presence of the second strong coupling laser beam [1][2][3][4]. This phenomenon has been observed in various experiments for three basic configurations of a three-level system: Λ-, V-, and ladder [5,6] (for the ladder configuration [7], Λ configuration [8] with extension to number of lower levels more than two, referred to as tripod ones [9]). This effect has potential applications in the protocols that create quantum memory for quantum computers [10].…”
