Quantum Diffusion in a Photonic Fibonacci Chain: From Localization to Ballistic Dynamics

Author(s): Jiankun Zhu, Yao Qin, Yuxiang Guo, Jizhou Wu, Sheng-Jun Yang, Yucheng Wang, and Jingyun Fan Quantum transport remains a central yet experimentally challenging problem in condensed matter and quantum physics. Here we report the first complete experimental characterization of the full spectrum of quantum transport behaviors in a one-dimensional Fibonacci chain—the paradigmatic quasicrystalli… [Phys. Rev.
