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…
Photonic scattering in 2D waveguide QED: Quantum Goos-Hänchen shift
Yongguan Ke, Zhenzhi Peng, Muhib Ullah +1
Quantum emitters coupled to traveling photons in waveguides, known as waveguide quantum electrodynamics (WQED), offer a powerful platform for understanding light-matter interaction…
Diagnosing Floquet Chern and anomalous topological insulators based on Bloch oscillations
Maowu Zuo, Yongguan Ke, Zhoutao Lei +1
It is challenging to distinguish Floquet Chern insulator (FCI) and Floquet anomalous topological insulator (FATI) because of their common features of chiral edge states and far awa…
Nonlinear topological pumping of edge solitons
Xinrui You, Liaoyuan Xiao, Yongguan Ke +1
We study how nonlinear strength affects topological pumping of edge solitons by using nonlinear Gross-Pitaevskii equation. For weak nonlinear strength, the introduction of nonlinea…
One-dimensional -classified topological crystalline insulator under space-time inversion symmetry
Ling Lin, Yongguan Ke, Chaohong Lee
We explore a large family of one-dimensional (1D) topological crystalline insulators (TCIs) classified by invariants protected by space-time inversion symmetry. This f…
