论文摘要
在这里，我们表明，在具有设计损失的完美周期性稳定性链中，连贯的随机步行可以表现出各种不同的异常转移状态，以依赖链的初始状态。特别是，对于任何给定的有限初始时间间隔，都有一组初始状态导致高症运输方式。此外，有一些初始状态允许一个人在给定的时间间隔内实现次延伸的制度甚至本地化，或者改变渐近的长期扩散率。我们展示了如何在Balk玻璃中的单模波导的激光编写网络中实际上实现这些异常运输方式，或者如何使用集成的光子平台实现耦合的单模波导的平面系统。
Here we show that a coherent random walk in a perfectly periodic chain of bosonic modes with designed loss can exhibit a variety of different anomalous transfer regimes in dependence on the initial state of the chain. In particular, for any given finite initial time-interval there is a set of initial states leading to a hyperballistic transport regime. Also, there are initial states allowing one to achieve a subdiffusive regime or even localization for a given time-interval, or change an asymptotic long-time diffusion rate. We show how these anomalous transport regimes can be practically realized in a laser-written network of single-mode waveguides in balk glass or how a planar system of coupled single-mode waveguides can be realized with an integrated photonic platform.
