Formation of rogue waves on the periodic background in a fifth-order nonlinear Schrodinger equation

We construct rogue wave solutions of a fifth-order nonlinear Schrodinger equation on the Jacobian elliptic function background. By combining Darboux transformation and the nonlinearization of spectral problem, we generate rogue wave solution on two different periodic wave backgrounds. We analyze the obtained solutions for different values of system parameter and point out certain novel features of our results. We also compute instability growth rate of both do and cn periodic background waves for the considered system through spectral stability problem. We show that instability growth rate decreases (increases) for dn-(cn) periodic waves when we vary the value of the elliptic modulus parameter. (C) 2021 Elsevier B.V. All rights reserved.
