摘要:

阶跃边缘附近的电子密度的弗里德尔振荡在微波台球中有类似的情况。一个随机的平面波模型,通常只适合于一个纯粹的混沌系统的本征函数,可以应用和测试的非纯粹的混沌动力系统与测量伪可积和混合动力学几何。结果表明,赝可积微波腔中的振荡与随机平面波模型相吻合。将混合系统的混沌状态与规则状态分离需要以多种方式将适当的相空间投影结合到建模中,以便与实验良好一致。

英文摘要:

Friedel oscillations of electron densities near step edges have an analog in microwave billiards. A random plane wave model, normally only appropriate for the eigenfunctions of a purely chaotic system, can be applied and is tested for non-purely-chaotic dynamical systems with measurements on pseudo-integrable and mixed dynamics geometries. It is found that the oscillations in the pseudo-integrable microwave cavity matches the random plane-wave modeling. Separating the chaotic from the regular states for the mixed system requires incorporating an appropriate phase space projection into the modeling in multiple ways for good agreement with experiment.
