Single-mode and intermodal higher-order nonclassicalities in two-mode Bose-Einstein condensates
Sandip Kumar Giri,Sandip Kumar Giri,Biswajit Sen,C. H. Raymond Ooi,Anirban Pathak,Anirban Pathak +5 more
TL;DR: In this paper, an analytic operator solution of a generalized quantum mechanical Hamiltonian of two-mode Bose-Einstein condensates is obtained for short-time dynamics and the same is used to investigate the nonclassical properties of the modes present in the system.
Journal ArticleDOI
Nonclassicality in two-mode BEC
TL;DR: In this paper, an analytic operator solution of a generalized quantum mechanical Hamiltonian of two-mode Bose Einstein condensates (BECs) is obtained and the same is used to investigate the nonclassical properties of the modes present in the system.
Journal ArticleDOI
Intermodal entanglement in Raman processes
Biswajit Sen,Sandip Kumar Giri,Swapan Mandal,C. H. Raymond Ooi,Anirban Pathak,Anirban Pathak +5 more
TL;DR: In this paper, the operator solution of a completely quantum mechanical Hamiltonian of the Raman processes is used to investigate the possibility of obtaining intermodal entanglement between different modes involved in different modes.
Journal ArticleDOI
Nonclassicality in an atom–molecule Bose–Einstein condensate: Higher-order squeezing, antibunching and entanglement
TL;DR: In this paper, the transient quantum statistical properties of the atoms and molecules in an atom-molecule BEC system are investigated by obtaining a third-order perturbative solution of the Heisenberg's equations of motion corresponding to the Hamiltonian of the system, where two atoms can collide to form a molecule.
Journal ArticleDOI
Higher-order two-mode and multimode entanglement in Raman processes
TL;DR: In this paper, the existence of higher-order entanglement in the stimulated and spontaneous Raman processes is established using the perturbative solutions of the Heisenberg equations of motion for various field modes that are obtained using the Sen-Mandal technique and a fully quantum mechanical Hamiltonian.
