Simulating Higher-Order Topological Insulators in Density Wave Insulators
Kuan-Sen Lin, Barry Bradlyn
Since the discovery of the Harper-Hofstadter model, it has been known that condensed matter systems with periodic modulations can be promoted to non-trivial topological states with…

Axionic Band Topology in Inversion-Symmetric Weyl-Charge-Density Waves
Benjamin J. Wieder, Kuan-Sen Lin, Barry Bradlyn
In recent theoretical and experimental investigations, researchers have linked the low-energy field theory of a Weyl semimetal gapped with a charge-density wave (CDW) to high-energ…

Topological Properties of Gapped Graphene Nanoribbons with Spatial Symmetries
Kuan-Sen Lin, Mei-Yin Chou
To date, almost all of the discussions on topological insulators (TIs) have focused on two- and three-dimensional systems. One-dimensional (1D) TIs manifested in real materials, in…
