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…
Linear interference and systematic soliton shape modulation by engineering plane wave background and soliton parameters
Sagardeep Talukdar, Riki Dutta, Gautam Kumar Saharia +1
We investigate linear interference of a plane wave with different localised waves using coupled Fokas-Lenells equation(FLE) with four wave mixing (FWM) term. We obtain localised wa…
Data driven localized wave solution of the Fokas-Lenells equation using modified PINN
Gautam Kumar Saharia, Sagardeep Talukdar, Riki Dutta +1
We investigate data driven localized wave solutions of the Fokas-Lenells equation by using physics informed neural network(PINN). We improve basic PINN by incorporating control par…
