Entanglement in a driven two-qubit system coupled to common cavity
Amit Dey
A system, comprised of a qubit pair coupled to a common cavity, is studied with the aim of establishing qubit entanglement. This study is the sequel of the paper Phys. Rev. A 111,…
Localization and delocalization in networks with varied connectivity
Tamoghna Ray, Amit Dey, Manas Kulkarni
We study the phenomenon of localization and delocalization in a circuit-QED network with connectivity varying from finite-range to all-to-all coupling. We find a fascinating interp…
Quantum signatures of chaos in a cavity-QED-based stimulated Raman adiabatic passage
Amit Dey
A nonlinear stimulated Raman adiabatic passage (STIRAP) is a fascinating physical process that dynamically explores chaotic and non-chaotic phases. In a recent paper Phys. Rev. Res…
Emergence of chaos and controlled photon transfer in a cavity-QED network
Amit Dey, Manas Kulkarni
We develop optimal protocols for efficient photon transfer in a cavity-QED network. This is executed through stimulated Raman adiabatic passage (STIRAP) scheme, where time-varying…
Interaction-induced instability and chaos in the photoassociative stimulated Raman adiabatic passage from atomic to molecular Bose-Einstein condensates
Amit Dey, Amichay Vardi
We study the effect of interactions on the conversion of atomic -to molecular Bose-Einstein condensates via stimulated Raman adiabatic passage. Both energetic instability during av…
Engineering indefinitely long-lived localization in cavity-QED arrays
Amit Dey, Manas Kulkarni
By exploiting the nonlinear nature of the Jaynes Cumming's interaction, one can get photon population trapping in cavity-QED arrays. However, the unavoidable dissipative effects in…
