Higher-order topological insulators in quasicrystals

R Chen, CZ Chen, JH Gao, B Zhou, DH Xu - Physical review letters, 2020 - APS
Current understanding of higher-order topological insulators (HOTIs) is based primarily on
crystalline materials. Here, we propose that HOTIs can be realized in quasicrystals …

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 …

Quadrupole topological photonic crystals

L He, Z Addison, EJ Mele, B Zhen - Nature communications, 2020 - nature.com
Quadrupole topological phases, exhibiting protected boundary states that are themselves
topological insulators of lower dimensions, have recently been of great interest. Extensions …

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 …
