A Meshfree Splitting Method for Soliton Dynamics in Nonlinear Schroedinger Equations [PDF]
, 2012 A new method for the numerical simulation of the so-called solitondynamics arising in a nonlinear Schroedinger equation in the semi-classical regime is proposed. For the time discretization a classical fourth-order splitting method is used.
