Chiral-symmetric higher-order topological phases of matter

WA Benalcazar, A Cerjan - Physical Review Letters, 2022 - APS
We introduce novel higher-order topological phases of matter in chiral-symmetric systems
(class AIII of the tenfold classification), most of which would be misidentified as trivial by …

Topological phase transitions in disordered electric quadrupole insulators

CA Li, B Fu, ZA Hu, J Li, SQ Shen - Physical Review Letters, 2020 - APS
We investigate disorder-driven topological phase transitions in quantized electric
quadrupole insulators in two dimensions. We show that chiral symmetry can protect the …

Higher-order topological hyperbolic lattices

YL Tao, Y Xu - Physical Review B, 2023 - APS
A hyperbolic lattice allows for any p-fold rotational symmetry, in stark contrast to a two-
dimensional crystalline material, where only 2-fold, 3-fold, 4-fold, or 6-fold rotational …

Structural-disorder-induced second-order topological insulators in three dimensions

JH Wang, YB Yang, N Dai, Y Xu - Physical Review Letters, 2021 - APS
Higher-order topological insulators are established as topological crystalline insulators
protected by crystalline symmetries. One celebrated example is the second-order …

Higher-order topological insulators in hyperbolic lattices

ZR Liu, CB Hua, T Peng, R Chen, B Zhou - Physical Review B, 2023 - APS
To explore the non-Euclidean generalization of higher-order topological phenomena, we
construct a higher-order topological insulator model in hyperbolic lattices by breaking the …

Chern insulator in a hyperbolic lattice

ZR Liu, CB Hua, T Peng, B Zhou - Physical Review B, 2022 - APS
