Nonlinearity mediated miscibility dynamics of mass-imbalanced binary Bose Einstein condensate for circular atomtronics
Sriganapathy Raghav, Suranjana Ghosh, Barun Halder +1
We explore the nonlinearity-induced and fractional revivals-driven miscibility dynamics of quasi-2D mass-imbalanced binary Bose-Einstein condensates, confined in a ring-shaped wave…
Tunneling and Revival of Anderson Localization in Bose-Einstein Condensate
Sriganapathy Raghav, Barun Halder, Pradosh Basu +1
We provide an analytical model to fabricate an exponential localization of a Bose-Einstein condensate under bichromatic optical lattice. Such localization is famously known as Ande…
Exact Solutions for Solitary Waves in a Bose-Einstein Condensate under the Action of a Four-Color Optical Lattice
B. Halder, S. Ghosh, P. Basu +3
We address dynamics of Bose-Einstein condensates (BECs) loaded into a one-dimensional four-color optical lattice (FOL) potential with commensurate wavelengths and tunable intensiti…
Matter-wave Fractional Revivals in a Ring Waveguide
Jayanta Bera, Suranjana Ghosh, Luca Salasnich +1
We report fractional revival phenomena in an ultracold matter wave inside a ring waveguide. The specific fractional revival times are precisely identified and corresponding spatial…
Mesoscopic Quantum Superposition of Generalized Cat State: A Diffraction limit
Suranjana Ghosh, Raman Sharma, Prasanta K. Panigrahi
The orthogonality of cat and displaced cat states, underlying Heisenberg limited measurement in quantum metrology, is studied in the limit of large number of states. The mesoscopic…
Enhanced Quantum Sensitivity in a Vibrating Diatomic Molecule due to Rotational Amendment
Suranjana Ghosh, Utpal Roy
Quantum sensitivity is an important issue in the field of quantum metrology where sub-Planck scale structures play crucial role in the Heisenberg limited measurement. We investigat…
