Through the nonlinear coupling interactions between atomic waves, the structure appears as the matter wave gratings, and diffracts its surrounding atomic waves.
通过原子波之间非线性耦合相互作用，这种结构可以表现为物质波光栅，对其周期的原子波产生衍射现。

In this paper, the nonlinear wave-wave interactions among the "pump" wave, "signal" wave aud "idle" wave have been discussed, starting from nonequilibrium theory.
本文从非平衡统计理论出发，讨论了三光子参量系统中泵浦波、信号波和空闲波之间的非线性波-波相互作用。

We investigate numerically the interactions of multiple partially incoherent spatial solitons in a nonlinear medium with logarithmic saturable nonlinearity based on the coherent density approach.
