Observation of boundary induced chiral anomaly bulk states and their transport properties

M Wang, Q Ma, S Liu, RY Zhang, L Zhang, M Ke… - Nature …, 2022 - nature.com
The most useful property of topological materials is perhaps the robust transport of
topological edge modes, whose existence depends on bulk topological invariants. This …

Dirac states in an inclined two-dimensional Su-Schrieffer-Heeger model

CA Li, SJ Choi, SB Zhang, B Trauzettel - Physical Review Research, 2022 - APS
We propose to realize Dirac states in an inclined two-dimensional Su-Schrieffer-Heeger
model on a square lattice. We show that a pair of Dirac points protected by space-time …
