Topological domain-wall states from Umklapp scattering in twisted bilayer graphene
Juncheng Li, Cong Chen, Wang Yao
Twistronics, harnessing interlayer rotation to tailor electronic states in van der Waals materials, has predominantly focused on small-angle regime. Here, we unveil the pivotal rol…

Spinless topological chirality from Umklapp scattering in twisted 3D structures
Cong Chen, Xu-Tao Zeng, Wang Yao
Spinless systems exhibit unique topological characteristics compared to spinful ones, stemming from their distinct algebra. Without chiral interactions typically linked to spin, an…
