Asymmetric Two-Way Gaussian Quantum Steering in Coupled Lossy Waveguides
Hafsa Zia, Haleema Sadia Qureshi, Shakir Ullah +2
Quantum steering is an important type of quantum correlation with potential applications in one-sided device-independent (1SDI) quantum information protocols. In this contribution,…
Multiple electromagnetically induced transparency, slow and fast light in hybrid optomechanics
M. Javed Akram, Fazal Ghafoor, Farhan Saif
We theoretically investigate the phenomenon of electromagnetically induced transparency (EIT) of a weak probe field in hybrid optomechanics with a single three-level (-type) ato…
Control of Fano resonances and slow light using Bose-Einstein condensates in a nanocavity
M. Javed Akram, Fazal Ghafoor, M. Miskeen Khan +1
In this study, a standing wave in an optical nanocavity with Bose-Einstein condensate (BEC) constitutes a one-dimensional optical lattice potential in the presence of a finite two…
Electromagnetically induced transparency and tunable fano resonances in hybrid optomechanics
Muhammad Javed Akram, Fazal Ghafoor, Farhan Saif
We explain the phenomena of electromagnetically induced transparency (EIT) of a weak probe field and tunable Fano resonances in hybrid optomechanics. The system of study consists o…
Slow and fast light dynamics in a chiral cold and hot atomic medium
Bakht A Bacha, Fazal Ghafoor, Rashid G Nazmidinov
We study Chiral Based Electromagnetically Induced Transparency (CBEIT) of a light pulse and its associated subluminal and superluminal behavior through a cold and a hot medium of 4…
Triplet absorption spectroscopy and electromagnetically induced transparency
F. Ghafoor, R. G. Nazmitdinov
Coherence phenomena in four-level atomic system, cyclicly driven by three coherent fields, are investigated thoroughly at zero and weak magnetic fields. Each strongly interacting a…
Superluminal light propagation in a bi-chromatically Raman-driven and Doppler-broadened N-type 4-level atomic system
Bakht Amin Bacha, Fazal Ghafoor, Iftikhar Ahmad
We investigate the behavior of fast light pulse propagation in an N-type Doppler-broadened 4-level atomic system using double Raman gain processes. This system displays novel and i…
Avoidance of instability of a superluminal Gaussian light pulse via control of nonlinear coherence Kerr effect in a gain-assisted medium
Bakht Amin Bacha, Fazal Ghafoor
We investigate nonlinear Kerr-induced coherence effect on a superluminal probing light pulse in a gain-assisted N-type 4-level atomic system via an intense monochromatic laser fiel…
Hole-burning in an Autler-Townes doublet and in superluminal (subluminal) Electromagnetically induced transparency of a light pulse via a joint nonlinear coherent Kerr effect and Doppler broadening
Bakhtt A Bacha, Fazal Ghafoor, Iftikhar Ahmad
We investigate the behavior of light pulse propagation in a 4-level double Lambda atomic system under condition of electromagnetically induced transparency. The Fano type interfere…
An alternative realization of spontaneous emission cancelation via Field Generated Coherence (FGC)
Fazal Ghafoor
In contrast to the traditional Spontaneous Generated Coherence (SGC), Field Generated Coherence (FGC)-based atomic scheme is presented for spontaneous emission cancellation. It is…
Autler-Townes multiplet spectroscopy
Fazal Ghafoor
We extend the concepts of the Autler-Townes doublet and triplet spectroscopy to quartuplet, quintuplet and suggest linkages in sodium atom in which to display these spectra. We exp…
