Topological corner states in graphene by bulk and edge engineering

J Zeng, C Chen, Y Ren, Z Liu, W Ren, Z Qiao - Physical Review B, 2022 - APS
Two-dimensional higher-order topology is usually studied in (nearly) particle-hole symmetric
models, so that an edge gap can be opened within the bulk one. But more often the edge …

Effects of pressure and temperature on topological electronic materials X 2 Y 3 (X= As, Sb, Bi; Y= Se, Te) using first-principles

L Fang, C Chen, X Lu, W Ren - Physical Chemistry Chemical Physics, 2023 - pubs.rsc.org
We systematically study the thermal and topological properties of X2Y3 (X= As, Sb, Bi; Y=
Se, Te) and the effects of pressure and temperature on their electronic properties using first …

Pressure-induced switching between topological phases in magnetic van der Waals heterostructures

J Li, P Yang, W Ren, R Wu - Physical Review B, 2024 - APS
Despite the significant developments in quantum anomalous Hall (QAH) insulators study in
recent years, it remains an outstanding challenge to tune between different topological …
