| 摘 要： | By making use of the split-step Fourier method, this paper numerically simulates dynamical behaviors, including repulsion, fusion, scattering and spiraling of colliding (3+1)D spatiotemporal solitons in both the dispersive medium with cubic-quintic and the saturable medium. Careful comparison of the colliding behaviors in these two media is presented. Although the origin of the nonlinearities is different in these two media, the obtained results show that the dynamical behaviors are very similar. This presents additional evidence to support the supposition of universality of interactions between solitons.

| Abstract: | By making use of the split-step Fourier method, this paper
numerically simulates dynamical behaviors, including repulsion,
fusion, scattering and spiraling of colliding (3+1)D spatiotemporal
solitons in both the dispersive medium with cubic-quintic and the
saturable medium. Careful comparison of the colliding behaviors in
these two media is presented. Although the origin of the
nonlinearities is different in these two media, the obtained results
show that the dynamical behaviors are very similar. This presents
additional evidence to support the supposition of universality of
interactions between solitons. |
