David Bindel, Maciej Zworski

AI总结:

研究一维散射问题,证明存在温和正势垒时,束缚态与反束缚态在1/h指数小误差内对称,并介绍高效计算共振的数值方案。

摘要:

我们考虑一维散射,并证明当存在一个将相互作用区域与无穷远分隔开的温和正势垒时,束缚态和反束缚态在1/h指数小误差内是对称的。这一简单结果源于一个数值实验,我们描述了一种在一维中高效计算共振的数值方案。

英文摘要:

We consider one dimensional scattering and show how the presence of a mild positive barrier separating the interaction region from infinity implies that the bound and antibound states are symmetric modulo exponentially small errors in 1/h. This simple result was inspired by a numerical experiment and we describe the numerical scheme for an efficient computation of resonances in one dimension.
