Nondegenerate bright solitons and their interactions in the generalized coupled nonlinear Schroedinger system
R. Ramakrishnan, Samudra Roy, S. Stalin +1
The paper derives non-degenerate bright soliton solutions for a generalized coupled nonlinear Schrödinger system, studies their breathing behavior, elastic and energy-sharing colli…

Integrable motion of curves associated with the Fokas-Lenells equation and related spin system
R. Ramakrishnan, Sagardeep Talukdar, M. Lakshmanan +1
In this article, we study the gauge equivalence between the integrable Fokas- Lenells equation (FLE) and an associated spin equation through a gauge transformation and the zero cur…

Bright soliton interactions in the variable coefficient Fokas-Lenells equation, Conservation laws, Modulation instability and Soliton tunneling
Sagardeep Talukdar, R. Ramakrishnan, Sudipta Nandy +1
We present here a study of the bright soliton dynamics in an inhomogeneous fibre by means of variable coefficient Fokas-Lenells equation with time varying dispersion, nonlinearity…
