“…The electromagnetically induced transparency (EIT), a quantum interference phenomenon, is related to increase in the transmission of a weak probe beam in presence of a strong coupling beam [1,2]. Since the conception of EIT, several applications of this phenomenon have attracted attention of researchers which include applications in optical communication network [3], optical switching devices [4,5], manipulation of group velocity of light and light storage [6][7][8][9][10], tight laser frequency locking [11], high resolution spectroscopy [12,13], atomic clocks [14], quantum information processing [15,16], highly sensitive magnetometery [17][18][19][20][21][22], velocimetry [23], etc.…”

The electromagnetically induced transparency (EIT) observations in two Λ-systems of 87 Rb atom, |5 2 S 1/2 F = 1 → |5 2 P 3/2 F = 1 ← |5 2 S 1/2 F = 2 and |5 2 S 1/2 F = 1 → |5 2 P 3/2 F = 2 ← |5 2 S 1/2 F = 2 , have been investigated in detail and the results are found consistent with our proposed theoretical models. The second Λ-system provides EIT signal with higher magnitude than the first system, both in absence and in presence of an applied magnetic field. The observed steeper slope of the EIT signal in presence of the magnetic field can enable one to achieve tight frequency locking of lasers using these EIT signals.

“…The advantages of this approach can be fully exploited if combined with high detection efficiency on a single-particle level, as accessible with cold metastable noble gas atoms [5]. Although all species of metastable noble gas atoms [5][6][7] can be used for this purpose, additional motivation for work with neon atoms arises from the fact that single-state preparation and the preparation of coherent superposition states have been previously studied extensively with this atomic species [8,9].…”

The coherent control of multi-partite quantum systems presents one of the central prerequisites in state-of-the-art quantum information processing. With the added benefit of inherent high-fidelity detection capability, atomic quantum systems in high-energy internal states, such as metastable noble gas atoms, promote themselves as ideal candidates for advancing quantum science in fundamental aspects and technological applications. Using laser-cooled neon atoms in the metastable $^3$P$_2$ state of state $1s^2 2s^2 2p^5 3s$ (LS-coupling notation) (Racah notation: $^2P_{3/2}\,3s[3/2]_2$) with five $m_F$-sublevels, experimental methods for the preparation of all Zeeman sublevels $\ket{m_J} = \ket{+2}, \ket{+1}, \ket{0}, \ket{-1}, \ket{-2}$ as well as the coherent control of superposition states in the five-level system $\ket{+2}, \ldots, \ket{-2}$, in the three-level system $\ket{+2}, \ket{+1}, \ket{0}$, and in the two-level system $\ket{+2}, \ket{+1}$ are presented. The methods are based on optimized radio frequency and laser pulse sequences. The state evolution is described with a simple, semiclassical model. The coherence properties of the prepared states are studied using Ramsey and spin echo measurements.

“…In contrast to EIT, the EIA is constructive quantum interference effect which enhances the absorption of the probe beam along with a large anomalous dispersion inside the medium. These two effects, EIT and EIA, offer potential applications in slow [3][4][5] and fast [6] light propagation, high resolution spectroscopy [7][8][9], sensitive magnetometory [10][11][12], precise atomic clocks [13], optical switching [14,15], enhanced non-linear optical processes [16,17], precise frequency locking [18], etc.…”

Coupling field dependent quantum interference effects in a Λ-system of 87Rb atom

et al. 2018

A Λ-system in D2 line transition of the 87 Rb atom has been investigated for quantum interference effects for different configurations of coupling field. With a travelling wave coupling field (copropagating with probe field), the probe beam shows the earlier known electromagnetically induced transparency (EIT) effect at the resonance. With a standing wave coupling field (which is co-and counter-propagating with probe beam), the probe EIT gets transformed into an electromagnetically induced absorption (EIA). A variation in coupling beam power has shown that, at high coupling power, EIA signals have much larger amplitude and slope than those of EIT signals with and without applied magnetic field. These EIA signals can be useful for tight laser frequency locking and optical switching.
