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…
Fokas-Lenells equation dark soliton and gauge equivalent spin equation
Riki Dutta, Sagardeep Talukdar, Gautam Kumar Saharia +1
We propose the Hirota bilinearization of the Fokas-Lenells derivative nonlinear Schrodinger equation with a non-vanishing background. The bilinear method is applied using an auxila…
Bilinearization of the Fokas-Lenells equation Conservation laws and soliton interactions
Sagardeep Talukdar, Riki Dutta, Gautam Kumar Saharia +1
In this paper, we propose the bilinearization of the Fokas-Lenells equation (FLE) with a vanishing boundary condition. In the proposed bilinearization we make use of an auxiliary f…
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…
