The discrete nonlinear Schrödinger equation (DNLS) is a fundamental mathematical model that describes the evolution of wave amplitudes in lattice systems where the interplay between dispersion and ...

Sometimes, it’s easy for a computer to predict the future. Simple phenomena, such as how sap flows down a tree trunk, are straightforward and can be captured in a few lines of code using what ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...
