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…

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…
