| 摘 要： | A high order energy preserving scheme for a strongly coupled nonlinear Schr¨odinger system is proposed by using the average vector field method. The high order energy preserving scheme is applied to simulate the soliton evolution of the strongly coupled Schr¨odinger system. Numerical results show that the high order energy preserving scheme can well simulate the soliton evolution, moreover, it preserves the discrete energy of the strongly coupled nonlinear Schr¨odinger system exactly.
