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…
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…
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…
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…
