$\mathbb{R}^3$中非线性薛定谔方程的孤子-势相互作用

Soliton-potential interactions for nonlinear Schrödinger equation in $\mathbb{R}^3$

Qingquan Deng, Avy Soffer, Xiaohua Yao

摘要:

本文主要研究$\mathbb{R}^3$中带势NLS方程的窄孤子的动力学和散射,其中系统的渐近态在参数空间中可以远离初态.具体地说,如果我们让一个具有初速度$\upsilon_{0}$的窄孤子态与一个额外的势$V(x)$相互作用,那么在无限时间内出射孤波的速度$\upsilon_{+}$一般会与$\upsilon_{0}$有很大的不同。与我们目前的工作相反,以前的工作证明了孤子是渐近稳定的假设下,$\upsilon_{+}$保持接近$\upsilon_{0}$以某种方式。

英文摘要:

In this work we mainly consider the dynamics and scattering of a narrow soliton of NLS equation with a potential in $\mathbb{R}^3$, where the asymptotic state of the system can be far from the initial state in parameter space. Specifically, if we let a narrow soliton state with initial velocity $\upsilon_{0}$ to interact with an extra potential $V(x)$, then the velocity $\upsilon_{+}$ of outgoing solitary wave in infinite time will in general be very different from $\upsilon_{0}$. In contrast to our present work, previous works proved that the soliton is asymptotically stable under the assumption that $\upsilon_{+}$ stays close to $\upsilon_{0}$ in a certain manner.
