External field effect on quantum features of radiation emitted by a QW in a microcavity
Eyob A. Sete, Sumanta Das, H. Eleuch
We consider a semiconductor quantum well in a microcavity driven by coherent light and coupled to a squeezed vacuum reservoir. By systematically solving the pertinent quantum Lange…
Quantum interference in timed Dicke basis and its effect on bipartite entanglement
Eyob A. Sete, Sumanta Das
We analyze the effect of position dependent excitation phase on the properties of entanglement between two qubits formed in atomic systems. We show that the excitation phase induce…
Quantum correlations and violation of Bell inequality induced by External Field in a two photon radiative cascade
Luqi Yuan, Sumanta Das
We study the polarization dependent second order correlation of a pair of photons emitted in a four level radiative cascade driven by an external field. It is found that the quantu…
Vacuum-Induced Coherence in Ultracold Photoassociative Ro-Vibrational Excitations
Sumanta Das, Arpita Rakshit, Bimalendu Deb
We show that coherence between two excited ro-vibrational states belonging to the same molecular electronic configuration arises quite naturally due to their interaction with elect…
Quantum interference controlled resonance profiles: From lasing without inversion to photo-detection
Konstantin E. Dorfman, Pankaj K. Jha, Sumanta Das
In this work we report a quantum interference mediated control of the resonance profiles in a generic three-level system and investigate its effect on key quantum interference (QI)…
