Abstract: Abstract The coupled nonlinear Schrodinger system with spatially modulated nonlinearities is discussed by the variable separation and ansatz methods. Two families of explicit vector vortices with arbitrary vorticity are generated. Some basic properties of the… read more here.

Abstract: This article presents the mathematical model of the unconditionally stable explicit transmission-line matrix (USE-TLM) method, which can operate at a time step beyond the Courant-Friedrichs–Lewy (CFL) limit. This technique is based on the eigenmode decomposition… read more here.
