Abstract :
In this paper, we propose a semi-explicit multi-symplectic scheme to solve the coupled nonlinear Schrödinger equation. The scheme is derived by multi-symplectic Fourier pseudospectral method in spatial discretization and Euler method in temporal discretization. It is verified that the obtained multi-symplectic scheme has corresponding discrete multi-symplectic conservation laws. Numerical experiments show the good preservation property of the proposed method during long-time numerical calculation.
