一维随机介质中延迟时间的标度特性
Scaling properties of delay times in one-dimensional random media
摘要:
研究了一维有限随机介质中Wigner延迟时间倒数矩的标度特性。我们发现,它们遵循一个简单的标度律,这是独立的随机势的微观细节。从一维无序线、光晶格到具有相关散射体的微波波导,我们的理论考虑在数值上得到了证实。
英文摘要:
The scaling properties of the inverse moments of Wigner delay times are investigated in finite one-dimensional (1D) random media with one channel attached to the boundary of the sample. We find that they follow a simple scaling law which is independent of the microscopic details of the random potential. Our theoretical considerations are confirmed numerically for systems as diverse as 1D disordered wires and optical lattices to microwave waveguides with correlated scatterers.
