Abstract

We study the role of unstable points in the Bohmian flow of a 2d system composed of two non-interacting harmonic oscillators. In particular, we study the unstable points in the inertial frame of reference as well as in the frame of reference of the moving nodal points, in cases with 1, 2 and multiple nodal points. Then, we find the contributions of the ordered and chaotic trajectories in the Born distribution, and when the latter is accessible by an initial particle distribution which does not satisfy Born's rule.

摘要

我们研究了由两个非相互作用的谐振子组成的二维系统在玻姆流中不稳定点的作用。特别地，我们研究了在惯性参考系以及移动节点参考系中的不稳定点，包括具有1个、2个和多个节点的情况。然后，我们在玻恩分布中找到了有序和混沌轨迹的贡献，以及当初始粒子分布不满足玻恩规则时后者是否可及的情况。
