Coherence-mediated squeezing of cavity field coupled to a coherently driven single quantum dot
Parvendra Kumar, Agnikumar G. Vedeshwar
Coherence has been remaining a key resource for numerous applications of quantum physics ranging from quantum metrology to quantum information. Here, we report a theoretical work o…
Cavity-assisted enhanced and dephasing immune squeezing in the resonance fluorescence of a single quantum dot
Parvendra Kumar, Agnikumar G. Vedeshwar
We theoretically demonstrate the enhanced and dephasing immune squeezing in the resonance fluorescence of a single quantum dot (QD) confined to a pillar-microcavity and driven by a…
Ultrafast and selective coherent population transfer in four-level atoms by a single frequency chirped few-cycle pulse
Parvendra Kumar, Amarendra K. Sarma
We report and propose a simple scheme to achieve the ultrafast and selective population transfer in four-level atoms by utilizing a single frequency chirped few-cycle pulse. It is…
Gaussian and sinc shaped few-cycle pulse driven ultrafast coherent population transfer in lambda- like atomic systems
Parvendra Kumar, Amarendra K. Sarma
We report and propose a simple scheme to achieve efficient and fast coherent population transfer (CPT) by utilizing either a nonlinearly chirped Gaussian shaped few-cycle laser pul…
Ultrafast and efficient coherence creation in Λ-like atomic systems driven by nonlinearly chirped few-cycle pulses
Amarendra K. Sarma, Parvendra Kumar
We report an ultrafast and efficient way to create the maximum coherence between the two lower states in a -like atomic systems, driven by two nonlinearly chirped few-cycle pulses.…
