Engineering Bright Solitons to Enhance the Stability of Two-Component Bose-Einstein Condensates
R. Radha, P. S. Vinayagam, J. B. Sudharsan +2
We consider a system of coupled Gross-Pitaevskii (GP) equations describing a binary quasi-one-dimensional Bose-Einstein condensate (BEC) with intrinsic time-dependent attractive in…
Persistent bright solitons in sign-indefinite coupled nonlinear Schrodinger equations with a time-dependent harmonic trap
R. Radha, P. S. Vinayagam, J. B. Sudharsan +1
We introduce a model based on a system of coupled nonlinear Schrodinger (NLS) equations with opposite signs infront of the kinetic and gradient terms in the two equations. It also…
Generalized gauge transformation approach to construct dark solitons of coupled nonlinear Schrodinger type equations
P. S. Vinayagam, R. Radha, Vivek M. Vyas +1
We harness the freedom in the celebrated gauge transformation approach to generate dark solitons of coupled nonlinear Schrödinger (NLS) type equations. The new approach which is pu…
An Analytical Window into the World of Ultracold Atoms
R. Radha, P. S. Vinayagam
We review the recent developments which had taken place in the domain of quasi one dimensional BECs from the viewpoint of integrability. To start with, we consider the dynamics of…
