In particular, we apply two symplectic integrators to the nonlinear Schrödinger equation, and we demonstrate that they are able to produce accurate results and to preserve very well the invariants of the original system, such as the energy and charge. | Source Title: | Computers and Mathematics with Applications | URI: | http://scholarbank.nus.edu.sg/handle/10635/104869 | ISSN: | 08981221 | DOI: | 10.1016/0898-1221(96)00136-8 |
