High second Chern number induced by long-range hopping in a four-dimensional Dirac model
Zheng-Rong Liu, Xiang Liu, Rui Chen +1
Four-dimensional (4D) topological systems provide a promising platform for exploring topological phenomena beyond three dimensions. So far, extensive recent studies on 4D topologic…
Numerical calculation of the -space second Chern number in four dimensions
Xiang Liu, Xiao-Xia Yi, Zheng-Rong Liu +2
We propose an efficient numerical method to compute the -space second Chern number in four-dimensional (4D) topological systems. Our approach employs an adaptive mesh refinement…
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,…
Five-dimensional Floquet topological semimetals with emergent Yang monopoles and linked Weyl surfaces
Zheng-Rong Liu, Rui Chen, Bin Zhou
Recently, Floquet topological matter has attracted significant attention for its potential to reveal novel topological phases inaccessible in static systems. In this paper, we inve…
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…
