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…
Shortcuts to adiabatic Thouless pumping
Wenjie Liu, Yongguan Ke, Chaohong Lee
Thouless pumping, the quantized transport of particles in a cyclic adiabatic evolution, faces a challenge: slow driving may exceed the coherent time, while fast driving may break q…
Correlated topological pumping of interacting bosons assisted by Bloch oscillations
Wenjie Liu, Shi Hu, Li Zhang +2
Thouless pumping, not only achieving quantized transport but also immune to moderate disorder, has attracted growing attention in both experiments and theories. Here, we explore ho…
Bloch-Landau-Zener dynamics in single-particle Wannier-Zeeman systems
Yongguan Ke, Xizhou Qin, Honghua Zhong +3
Stimulated by the experimental realization of spin-dependent tunneling via gradient magnetic field [Phys. Rev. Lett. 111, 225301 (2013); Phys. Rev. Lett. 111, 185301 (2013)], we in…
Statistics-dependent quantum co-walking of two particles in one-dimensional lattices with nearest-neighbor interactions
Xizhou Qin, Yongguan Ke, Xiwen Guan +3
We investigate continuous-time quantum walks of two indistinguishable particles [bosons, fermions or hard-core bosons (HCBs)] in one-dimensional lattices with nearest-neighbor inte…
