By use of this method, we can not only obtain the propagation matrix of atom beam in free space under the influence of gravity, but also obtain the interaction matrix of atom beam with and pulse.
The fiber propagation model can be described by the nonlinear Schrodinger equation, and the split-step Fourier method is used extensively to solve the pulse-propagation problem.
