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…
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…
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…
