通过实验和理论研究了波在具有利维飞行可能性的一维随机介质中所花费的时间。研究了正则无序系统中量子波和经典波的扩散动力学。我们证明了一类广泛的无序——Levy无序——导致了延迟时间的强随机波动；然而，分布的尾部和延迟时间的平均值对Levy航班不敏感。我们的结果揭示了超越标准布朗波扩散的波传播的普遍特征。
The time that waves spend inside 1D random media with the possibility of performing Levy flights is experimentally and theoretically studied. The dynamics of quantum and classical wave diffusion has been investigated in canonical disordered systems via the delay time. We show that a wide class of disorder--Levy disorder--leads to strong random fluctuations of the delay time; nevertheless, the tail of the distribution and the average of the delay time are insensitive to Levy flights. Our results reveal a universal character of wave propagation that goes beyond standard Brownian wave-diffusion.
