“…2 The external fields are tuned to their angular frequencies and atomic state resonance frequencies as: ∆ 1 = ω 12 − ω 1 , ∆ 2 = ω 14 − ω 2 , ∆ p = ω 35 − ω p and ∆ m = ω 13 − ω m of the system. The following Von-Neumann equation of density matrix is to measure coherence between two states [29][30][31]:…”

The birefringence characteristics of reflection and transmission of light pulse are explored in chiral medium driving by two probe electric and magnetic fields, while four control fields. The proposed medium show significant birefringence behaviors in reflection/transmission and Goos-Hänchen (GH) shifted beams. The birefringent GH-reflected and GH-transmitted pulses show significant contribution in the space time gap creation for secure communication and invisibility. A space-time gap has been observed in the reflection, transmission and corresponding GH-shifted reflection and transmission birefringent beams. The theoretical results may be useful for noise free secure communication in invisible radar technology.

A coherent atomic medium is proposed for manipulating the absorption, dispersion, transmission and reflection of an optical soliton via two strong coherent control field's Rabi oscillations, detunings and incident angles. Significant anomalous dispersion regions and a negative group index are investigated. A group index of n g =−1500 and a negative group velocity of v g =−2.0×10 5 ms −1 is calculated. This leads to superluminal propagation (v g >c) in the anomalous dispersion region. A significant cancellation of linear and nonlinear effects results a bright optical soliton in the coherent atomic medium. Similarly the shape-preserving phenomenon of the bright optical solitons is investigated by launching the input pulse at different incident angles. As a result, the intensity distribution of the optical solitons has no fluctuation in time t/τ 0 with any values of y/ω 0 and shows a significant bright form of solitary waves. These solitons show remarkable applications in optics, particularly in soliton radar technology for medical purposes, controlling the intensity of bright solitons for the modification of optical information processing, high-speed optical switching and quantum communication.

This manuscript investigates atomic microscopy at the interface ofa silver silica $AgSiO_2$ nano-composite and cesium atomic mediumusing surface plasmon polariton dispersion relation. The studyreveals the measurement of sharp localization peaks on both thereal and imaginary parts of the dispersion relation of SPPs. Asharp single localization peak is reported in sub-half wave lengthdomain having minimum uncertainty in position with high precisionprobability. The study also reveals double, triple, four, and evenfive localized peaks in one wavelength domain with the highintensity of control field. The localization probability at theimaginary part ranges from $30-35\%$, while the real part rangesfrom $96-98\%$ on the dispersion relation of SPPs. Thesignificance of this work is that the localization probability isenhanced with the volume fractional change of the nano-particlewithout disturbing the position uncertainty.
