Bohmian轨线的动力系统方法

A dynamical systems approach to Bohmian trajectories

F. Borondo, A. Luque, J. Villanueva, D. A. Wisniacki

摘要:

众所周知,在量子力学的德布罗意-玻姆形式主义的框架内定义的量子轨道的动力学中,涡旋起着关键作用。它已被严格证明,在相关的速度场中的旋涡运动可以诱导这些轨迹的混沌,和数值研究已经探索了丰富的各种行为,由于它们的影响,可以观察到。在本文中,我们更进一步,并显示如何动力系统的理论可以用来构建一个一般的和系统的分类,这样的动力学行为。这将有助于建立一些坚实的基础上,玻姆的量子轨道的内在随机性的研究可以根据。最后以二维各向同性谐振子为例进行了说明。

英文摘要:

Vortices are known to play a key role in the dynamics of the quantum trajectories defined within the framework of the de Broglie-Bohm formalism of quantum mechanics. It has been rigourously proved that the motion of a vortex in the associated velocity field can induce chaos in these trajectories, and numerical studies have explored the rich variety of behaviors that due to their influence can be observed. In this paper, we go one step further and show how the theory of dynamical systems can be used to construct a general and systematic classification of such dynamical behaviors. This should contribute to establish some firm grounds on which the studies on the intrinsic stochasticity of Bohm's quantum trajectories can be based. An application to the two dimensional isotropic harmonic oscillator is presented as an illustration.
