Numerical study of nonlinear Schrodinger and coupled Schrodinger equations by differential transformation method

This paper presents the coupled version of a previous work on nonlinear Schrodinger equation [23]. It focuses on the construction of approximate solutions of nonlinear Schrodinger equations. In this paper, we applied the differential transformation method (DTM) to solving coupled Schrodinger equations. The obtained results show that the technique suggested here is accurate and easy to apply. (C) 2010 Elsevier B.V. All rights reserved.
