Tunable cornerlike states in topological type-II hyperbolic lattices
Zheng-Rong Liu, Tan Peng, Xiang Liu +4
Type-II hyperbolic lattices constitute a new class of hyperbolic structures that are projected onto the Poincaré ring and possess both an inner and an outer boundary. In this work,…
Structural disorder-induced topological phase transitions in quasicrystals
Tan Peng, Yong-Chen Xiong, Chun-Bo Hua +8
Recently, the structural disorder-induced topological phase transitions in periodic systems have attracted much attention. However, in aperiodic systems such as quasicrystalline sy…
Periodically driven four-dimensional topological insulator with tunable second Chern number
Zheng-Rong Liu, Rui Chen, Bin Zhou
In recent years, Floquet engineering has attracted considerable attention as a promising approach for tuning topological phase transitions. In this work, we investigate the effects…
Four-dimensional Floquet topological insulator with an emergent second Chern number
Zheng-Rong Liu, Rui Chen, Bin Zhou
Floquet topological insulators have been widely investigated in lower-dimensional systems. However, Floquet topological insulators induced by time-periodic driving in higher-dimens…
