Nonlinear topological laser based on multipole insulators
Zi-Yuan Li, Zi-Xiang Hu, Qi Li
Two-dimensional higher-order topological insulators (HOTIs), characterized by distinctive one-dimensional edge states and zero-dimensional corner states, provide an ideal platform…
Disorder effects in two-dimensional flat-band system with next-nearest-neighbor hopping
Yue Heng Liu, Zi-Xiang Hu, Qi Li
For two-dimensional Lieb lattice, while intrinsic spin-orbit coupling is responsible for opening the gap that exhibits the quantum spin Hall effect, topological phase transitions a…
The geometric impact of the quantum Hall interface on a cone
Jie Li, Qi Li, Zi-Xiang Hu
Recently, quantum Hall interface has become a popular subject of research; distinct from that of the quantum Hall edge, which is constrained by external background confinement, the…
Fractional quantum Hall interface induced by geometric singularity
Qi Li, Yi Yang, Zhou Li +2
The geometric response of quantum Hall liquids is an important aspect to understand their topological characteristics in addition to the electromagnetic response. According to the…
Non-perturbative dynamics of flat-band systems with correlated disorder
Qi Li, Junfeng Liu, Ke Liu +2
We develop a numerical method for the time evolution of Gaussian wave packets on flat-band lattices in the presence of correlated disorder. To achieve this, we introduce a method t…
The entanglement entropy of the quantum Hall edge and its geometric contribution
Dan Ye, Yi Yang, Qi Li +1
Generally speaking, the entanglement entropy (EE) between two subregions of a gapped quantum many-body state is proportional to the area/length of their interface due to the short…
