Weak ergodicity breaking without nonthermal eigenstates
Boning Huang, Yongguan Ke, Li Zhang +2
The typical mechanisms of ergodicity breaking in isolated interacting quantum systems, such as many-body localization and quantum many-body scars, originate from the nonthermal nat…

Localization and scattering of a photon in quasiperiodic qubit arrays
Xinyin Zhang, Yongguan Ke, Zhengzhi Peng +4
We study the localization and scattering of a single photon in a waveguide coupled to qubit arrays with quasiperiodic spacings. As the quasiperiodic strength increases, localized s…
