非线性Schrodinger / Gross-Pitaevskii方程的动力学研究含孤子和简并中性模系统的质量传递

Dynamics of Nonlinear Schrodinger / Gross-Pitaevskii Equations; Mass Transfer in Systems with Solitons and Degenerate Neutral Modes

Zhou Gang, Michael Weinstein

摘要:

非线性薛定谔/ Gross-Pitaevskii方程在理解非线性光学和宏观量子系统中起着核心作用。这种系统的大时间动力学由非线性基态流形、离散中性模("激发态“)和色散辐射的相互作用控制。具有对称性的系统,在大于一的空间维度上,通常具有简并中性模式。因此,我们研究了具有退化中性模的系统的大时间动力学。这就需要一个新的规范形式(非线性矩阵费米黄金法则)来控制系统的大时间渐近弛豫到基态(孤子)流形。

英文摘要:

Nonlinear Schrodinger / Gross-Pitaevskii equations play a central role in the understanding of nonlinear optical and macroscopic quantum systems. The large time dynamics of such systems is governed by interactions of the nonlinear ground state manifold, discrete neutral modes (``excited states'') and dispersive radiation. Systems with symmetry, in spatial dimensions larger than one, typically have degenerate neutral modes. Thus, we study the large time dynamics of systems with degenerate neutral modes. This requires a new normal form (nonlinear matrix Fermi Golden Rule) governing the system's large time asymptotic relaxation to the ground state (soliton) manifold.
