经典和量子动力学KS熵的Hamilton-Jacobi公式

Hamilton-Jacobi Formulation of KS Entropy for Classical and Quantum Dynamics

M. Hossein Partovi

摘要:

一个哈密顿-雅可比制定的李雅普诺夫谱和KS熵。它在数值上是有效的,揭示了KS不变量与经典作用量之间的密切关系。这个公式被扩展到量子域使用与薛定谔方程相关的马德隆-玻姆轨道。对于一个给定的轨道,所得到的量子KS不变量等于沿着轨道的概率密度的平均衰减率,而它的系综平均测量量子系统的构型空间信息的平均增长率。

英文摘要:

A Hamilton-Jacobi formulation of the Lyapunov spectrum and KS entropy is developed. It is numerically efficient and reveals a close relation between the KS invariant and the classical action. This formulation is extended to the quantum domain using the Madelung-Bohm orbits associated with the Schroedinger equation. The resulting quantum KS invariant for a given orbit equals the mean decay rate of the probability density along the orbit, while its ensemble average measures the mean growth rate of configuration-space information for the quantum system.
