Higher order complex cubic quintic Ginzburg Landau equation : Chirped solitary waves
Naresh Saha, Baranana Roy, Avinash Khare
Propagation characteristics of the chirped dissipative solitary waves are investigated within the framework of higher order complex cubic quintic Ginzburg Landau equation. Potentia…
Dipole and quadrupole nonparaxial solitary waves
Naresh Saha, Barnana Roy, Avinash Khare
The cubic nonlinear Helmholtz equation with third and fourth order dispersion and non-Kerr nonlinearity like the self steepening and the self frequency shift is considered. This mo…
Chirped Elliptic Waves: Coupled Helmholtz Equations
Naresh Saha, Barnana Roy, Avinash Khare
Exact chirped elliptic wave solutions are obtained within the framework of coupled cubic nonlinear Helmholtz equations in the presence of non-Kerr nonlinearity like self steepening…
Coupled Helmholtz Equations : Chirped Solitary Waves
Naresh Saha, Barnana Roy, Avinash Khare
We investigate the existence and stability properties of the chirped gray and anti-dark solitary waves within the framework of coupled cubic nonlinear Helmholtz equation in the pre…
Confluent Second-Order Supersymmetric Quantum Mechanics and Spectral Design
David J. Fernandez C, Barnana Roy
The confluent second-order supersymmetric quantum mechanics, in which the factorization energies tend to a common value, is used to generate Hamiltonians with known spectra departi…
DARBOUX partners of pseudoscalar Dirac potentials associated with exceptional orthogonal polynomials
Axel Schulze-Halberg, Barnana Roy
We introduce a method for constructing Darboux (or supersymmetric) pairs of pseudoscalar and scalar Dirac potentials that are associated with exceptional orthogonal polynomials. Pr…
