Isotopic variations and Zeeman-like splitting in the spectra of nonlinear photonic meta-atoms
S. Zhang, I. Babushkin, U. Morgner +2
We study photonic meta-atoms, a unique class of composite solitary wave, supported in nonlinear waveguides. We establish an analogy to one-dimensional soft-core atoms, allowing to…

SWtools: A Python module implementing iterative solvers for soliton solutions of nonlinear Schrödinger-type equations
O. Melchert, A. Demircan
Solitons are ubiquitous in nature and play a pivotal role in the structure and dynamics of solutions of nonlinear propagation equations. In many instances where solitons exist, ana…

Numerical investigation of a family of solitary-wave solutions for the nonlinear Schrödinger equation perturbed by third-, and fourth-order dispersion
O. Melchert, A. Demircan
We study solitary wave solutions for the nonlinear Schrödinger equation perturbed by the effects of third-, and fourth-order dispersion, maintaining a wavenumber gap between the so…
