PT-invariant nonlocal variable-coefficient Fokas-Lenells equation: nonstandard Hirota bilinearization, symmetry-preserving and breaking multi-soliton solutions
Sagardeep Talukdar, Ramakrishnan R, Sudipta Nandy +1
In this paper, we explore a variable-coefficient Fokas-Lenells system with gain/loss. Applying a nonlocal symmetry reduction, the system leads to a PT-invariant variable-coefficien…
Nondegenerate bright solitons and their interactions in the generalized coupled nonlinear Schroedinger system
R. Ramakrishnan, Samudra Roy, S. Stalin +1
It is known that the generalized coupled nonlinear Schroedinger (GCNLS) equations can be reduced to the basic vector nonlinear Schroedinger models through various symmetry reductio…
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…
