| 相关介绍： | 摘要(abstract) the nonlinear schrödinger equation (nlse) is one of the most widely
applicable equations in physical science, and is used to characterize
nonlinear dispersive waves, plasmas, nonlinear optics, water waves,
and the dynamics of molecules. in this talk, we present a linearized
finite difference scheme for solving nonlinear schrödinger equations,
which is obtained based on the generalized finite-difference
time-domain method. the new scheme is shown to satisfy the discrete
analogous form of conservation law and is tested by two examples of
soliton propagation and collision. compared with other popular
existing methods, numerical results demonstrate that the present
scheme provides a more accurate solution.
