Bright soliton dynamics in Spin Orbit-Rabi coupled Bose-Einstein condensates
P. S. Vinayagam, R. Radha, S. Bhuvaneswari +2
We investigate the dynamics of a spin-orbit (SO) coupled BECs in a time dependent harmonic trap and show the dynamical system to be completely integrable by constructing the Lax pa…
Manipulation of light in a generalized coupled Nonlinear Schrodinger equation
R. Radha, P. S. Vinayagam, K. Porsezian
We investigate a generalized coupled nonlinear Schrodinger (GCNLS) equation containing Self-Phase Modulation (SPM), Cross-Phase Modulation (XPM) and Four Wave Mixing (FWM) describi…
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…
