摘要:

对于经典的台球,我们建议,一个矩阵的行动或长度的轨道结合统计措施,水平间距分布和频谱刚度,可以用来区分混沌的可积系统。作为二维混沌台球的例子,我们考虑了Bunimovich体育场台球和西奈台球。在能级间距分布和光谱刚度,我们发现GOE行为与随机矩阵理论的预测一致。我们研究了输运性质并计算了扩散系数。对于西奈台球,我们发现正常的扩散,而体育场台球表现出异常的扩散行为。作为二维可积台球的例子,我们考虑矩形台球。我们发现非常严格的行为与强相关的光谱类似的狄拉克comb.These研究结果提出的数值证据的普遍性水平间距波动举行的经典可积系统和经典完全混沌系统。

英文摘要:

For classical billiards we suggest that a matrix of action or length of trajectories in conjunction with statistical measures, level spacing distribution and spectral rigidity, can be used to distinguish chaotic from integrable systems. As examples of 2D chaotic billiards we considered the Bunimovich stadium billiard and the Sinai billiard. In the level spacing distribution and spectral rigidity we found GOE behaviour consistent with predictions from random matrix theory. We studied transport properties and computed a diffusion coefficient. For the Sinai billiard, we found normal diffusion, while the stadium billiard showed anomalous diffusion behaviour. As example of a 2D integrable billiard we considered the rectangular billiard. We found very rigid behaviour with strongly correlated spectra similar to a Dirac comb. These findings present numerical evidence for universality in level spacing fluctuations to hold in classically integrable systems and in classically fully chaotic systems.
