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…
Simultaneous control of optical dipole force and coherence creation by super-Gaussian femtosecond pulses in lambda-like atomic systems
Pawan Kumar, Parvendra Kumar, Amarendra K. Sarma
We report a study on the optical dipole force on a beam of neutral three-level like atomic system induced by a femtosecond super-Gaussian pulse. We show that maximum coherence betw…
