开放混沌台球中避免水平交叉的统计量

Avoided level crossing statistics in open chaotic billiards

Charles Poli, Barbara Dietz, Olivier Legrand, Fabrice Mortessagne, Achim Richter

摘要:

我们研究了一个具有大量开放衰变通道的两能级模型,以描述开放混沌台球中避免的能级交叉统计。这个模型使我们能够描述的基本变化的概率分布的避免水平交叉相比,封闭的情况下。给出了保留和破缺TRS系统的显式表达式。我们发现,衰减过程中引起的修改,在小间距的概率分布的避免水平交叉,由于共振的吸引力。理论预测与Dietz \textit{et al.}(Phys. Rev. E { \bf 73}(2006)035201)最近的实验结果完全一致。

英文摘要:

We investigate a two-level model with a large number of open decay channels in order to describe avoided level crossing statistics in open chaotic billiards. This model allows us to describe the fundamental changes of the probability distribution of the avoided level crossings compared with the closed case. Explicit expressions are derived for systems with preserved and broken Time Reversal Symmetry (TRS). We find that the decay process induces a modification at small spacings of the probability distribution of the avoided level crossings due to an attraction of the resonances. The theoretical predictions are in complete agreement with the recent experimental results of Dietz \textit{et al.} (Phys. Rev. E {\bf 73} (2006) 035201).
