非线性薛定谔方程的显式呼吸子解

Explicit breather solution of the nonlinear Schrödinger equation

Robert Conte, ENS Paris-Saclay

摘要:

给出了非线性薛定谔方程的三参数呼吸子的一条直线的封闭形式表达式。这为实验中观察到的时间倍周期提供了分析证明。在光纤中产生的某些脉冲确实是这种广义呼吸子的实验检验将大大简化。

英文摘要:

We present a one-line closed form expression for the three-parameter breather of the nonlinear Schrödinger equation. This provides an analytic proof of the time period doubling observed in experiments. The experimental check that some pulses generated in optical fibers are indeed such generalized breathers will be drastically simplified.
