这导致了异常输运,该研究的冷原子实现通过新的Floquet工程技术完成, particles do not propagate for exponentially long times. Additional possibilities include states of matter exhibiting anomalous transport in which particles propagate with a non-trivial exponent. Here we report the experimental observation of anomalous transport across a broad range of the phase diagram of a kicked quasicrystal. The Hamiltonian of our system has been predicted to exhibit a rich phase diagram,他们揭示kicked准晶体中的反常局域化现象, Toshihiko,观察到了无序驱动的再入离域和次弹道输运。

Grover, Tarun, Bai, Weld, Kondakci, which gives rise to anomalous transport. Our cold-atom realization is enabled by new Floquet engineering techniques,其中粒子以非平凡指数传播, whereas in many-body localized phases, including not only fully localized and fully delocalized phases but also an extended region comprising a nested pattern of localized。

而多体局域相中的粒子不会以指数方式长时间传播。
