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,…
Evaluation of real-space second Chern number using the kernel polynomial method
Rui Chen, Bin Zhou
We evaluate the real-space second Chern number of four-dimensional Chern insulators using the kernel polynomial method. Our calculations are performed on a four-dimensional system…
Anomalous Hall effects in magnetic weak topological insulator films
Rui Chen, Xiao-Xia Yi, Bin Zhou +1
The interplay between magnetism and strong topological insulator gives rise to distinct new topological phases and various intriguing phenomena, attracting significant attention in…
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…
