Formation of Solitonic Bound State via Light-Matter Interaction
Priyam Das, Ayan Khan, Anirban Pathak
Exchange of energy by means of light-matter interaction provides a new dimension to various nonlinear dynamical systems. Here, the effects of light-matter interaction are investiga…
Quantum State Transfer through Coherent Atom-Molecule Conversion in Bose-Einstein Condensate
Subhrajit Modak, Priyam Das, Prasanta K. Panigrahi
We demonstrate complete quantum state transfer of an atomic Bose-Einstein condensate to molecular condensate, mediated by solitonic excitations in a cigar shaped mean-field geometr…
Lattice induced stripe phase in Bose-Einstein condensate under non-inertial and inertial motion
Priyam Das
We consider a parametrically forced Bose-Einstein condensate in the combined presence of an optical lattice and harmonic oscillator potential in the mean field approach. A spatial…
Collectively induced many-vortices topology via rotatory Dicke quantum phase transition
Priyam Das, Mehmet Emre Tasgin, Ozgur E. Mustecaplioglu
We examine the superradiance of a Bose-Einstein condensate pumped with a Laguerre-Gaussian laser of high winding number, e.g., . The laser beam transfers its orbital angu…
Topology of Quantum Grey Soliton in Multi-Component Inhomogeneous Bose-Einstein Condensates
Priyam Das, Ayan Khan, Prasanta K. Panigrahi
We study the dispersion mechanism of Lieb mode excitations of both single and multi component ultra-cold atomic Bose gas, subject to a harmonic confinement through chirp management…
Controlled Generation of Nonlinear Resonances through Sinusoidal Lattice Modes in Bose-Einstein Condensate
Priyam Das, Prasanta K. Panigrahi
We study Bose-Einstein condensate in the combined presence of time modulated optical lattice and harmonic trap in the mean-field approach. Through the self-similar method, we show…
New cross-phase modulated localized solitons in coupled atomic-molecular BEC
Challenger Mishra, Priyam Das, Krishna Rai Dastidar +1
The interacting atom-molecule BEC (AMBEC) dynamics is investigated in the mean field ap- proach. The presence of atom-atom, atom-molecule and molecule-molecule interactions, couple…
Chirp Control of Sinusoidal Lattice Modes in Bose-Einstein Condensate
Priyam Das, Prasanta K. Panigrahi
A parametrically forced Bose-Einstein condensate (BEC) is studied in the mean field approach for the case of a general moving optical lattice. The interaction between the atoms in…
Effect of an Impurity on Grey Soliton Dynamics in Cigar-Shaped Bose-Einstein Condensate
Priyam Das, Sumona Gangopadhyay, Prasanta K. Panigrahi
In a cigar shaped Bose-Einstein condensate, explicit solutions of the coupled mean-field equations, describing defect-grey soliton dynamics are obtained, demonstrating the coexiste…
