 Nonlinear Schrödinger equation

The Nonlinear Schrödinger Equation (NLS) is a fundamental equation in quantum mechanics and mathematical physics that describes the evolution of a complex wave function in nonlinear media. It is a generalization of the linear Schrödinger equation, which describes the behavior of quantum mechanical systems. The NLS model is particularly important in contexts such as nonlinear optics, fluid dynamics, and plasma physics.
