Deterministic nonlinear bunching of bosons
Kingshuk Adhikary, Darren W. Moore, Radim Filip
The ability of bosonic energy quanta to bunch together in an energy-conserving interaction is a fundamental feature of quantum harmonic oscillators. Linear systems together with me…
Engineered non-Gaussian Coherence as a Thermodynamic Resource for Quantum Batteries
Kingshuk Adhikary
Accessing quantum advantage (QA) is a legitimate task in energy harvesting devices, and it is potentially reshaping thermodynamic concepts. In this respect, the resourceful quantum…
Characterizing quantum synchronization in the van der Pol oscillator via tomogram and photon correlation
Kingshuk Adhikary, K. M. Athira, M. Rohith
Scalable methods for detecting and quantifying the nonclassical nature of a quantum state in noisy environments are challenging due to a complex relationship between noise and quan…
Coherence of quantum non-Gaussian states via nonlinear absorption of quanta
Kingshuk Adhikary, Darren W. Moore, Radim Filip
The linear and phase insensitive absorption of a single quanta via coherent interactions with a saturable system, even a single ground state qubit, is sufficient to deterministical…
Dynamic structure factor of a driven-dissipative Bose-Hubbard model
Subhanka Mal, Anushree Dey, Kingshuk Adikary +1
Dynamic structure factor (DSF) is important for understanding excitations in many-body physics; it reveals information about the spectral and spatial correlations of fluctuations i…
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…
Number-phase uncertainty and quantum dynamics of bosons and fermions interacting with a finite range and large scattering length in a double-well potential
Kingshuk Adhikary, Subhanka Mal, Bimalendu Deb +3
We define the standard quantum limit (SQL) for phase and number fluctuations, and describe two-mode squeezing for number and phase variables. When phase is treated as a unitary qua…
