Matter-wave phase operators for quantum atom optics: On the possibility of experimental verification
Kingshuk Adhikary, Subhanka Mal, Abhik Kr. Saha +1
In early 90's Mandel and coworkers performed an experiment \cite{mandel} to examine the significance of quantum phase operators by measuring the phase between two optical fields. W…
Time- and frequency-domain two-particle correlations of a driven dissipative Bose-Hubbard model
Kingshuk Adhikary, Anushree Dey, Arpita Pal +2
We theoretically investigate the time- and frequency-domain two-particle correlations of a driven dissipative Bose-Hubbard model (BHM) at and near a dissipative phase transition (D…
Modeling atom-atom interactions at low energy by Jost-Kohn potentials
Subhanka Mal, Kingshuk Adhikary, Dibyendu Sardar +2
More than 65 years ago, Jost and Kohn [R. Jost and W. Kohn, {Phys. Rev.} {\bf 87}, 977 (1952)] derived an explicit expression for a class of short-range model potentials from a giv…
The effects of trap-confinement and interatomic interactions on Josephson effects and macroscopic quantum self-trapping for a Bose-Einstein Condensate
Abhik Kumar Saha, Kingshuk Adhikary, Subhanka Mal +2
We theoretically study the effects of trap-confinement and interatomic interactions on Josephson oscillations (JO) and macroscopic quantum self-trapping (MQST) for a Bose-Einstein…
Fermionic vs. bosonic two-site Hubbard models with a pair of interacting cold atoms
Subhanka Mal, Kingshuk Adhikary, Bimalendu Deb
In a recent work, Murmann {\it et. al.} [Phys. Rev. Lett. {\bf114}, 080402 (2015)] have experimentally prepared and manipulated a double-well optical potential containing a pair of…
