Topological phase transition from trigonal warping in van der Waals multilayers
Junjie Zeng, Yafei Ren, Kunhua Zhang +1
In van der Waals multilayers of triangular lattice, trigonal warping occurs universally due to the interlayer hopping. We theoretically investigate the effect of trigonal warping u…

Single-Valley Engineering in Graphene Superlattices
Yafei Ren, Xinzhou Deng, Changsheng Li +5
The two inequivalent valleys in graphene preclude the protection against inter-valley scattering offered by an odd-number of Dirac cones characteristic of Z2 topological insulator…
