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…

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…
