Layer Hall counterflow as a model probe of magic-angle twisted bilayer graphene
Jihang Zhu, Dawei Zhai, Cong Xiao +1
The recent constructions of flat moiré minibands in specifically twisted multilayer graphene and twisted transition metal dichalcogenides (TMDs) have facilitated the observation of…
Interlayer electric multipoles induced by in-plane field from quantum geometric origins
Huiyuan Zheng, Dawei Zhai, Cong Xiao +1
We show that interlayer charge transfer in 2D materials can be driven by an in-plane electric field, giving rise to electrical multipole generation in linear and second order of in…
Crossed Nonlinear Dynamical Hall Effect in Twisted Bilayers
Cong Chen, Dawei Zhai, Cong Xiao +1
We propose a novel nonlinear dynamical Hall effect characteristic of layered materials with chiral symmetry, which is driven by the joint action of in-plane and time variation of o…
Single photon emitters with polarization and orbital angular momentum locking in monolayer semiconductors
Di Zhang, Sha Deng, Dawei Zhai +2
Excitons in monolayer transition metal dichalcogenide are endowed with intrinsic valley-orbit coupling between their center-of-mass motion and valley pseudospin. When trapped in a…
Topological flat bands in strained graphene: substrate engineering and optical control
Md Tareq Mahmud, Dawei Zhai, Nancy Sandler
The discovery of correlated phases in twisted moiré superlattices accelerated the search for low-dimensional materials with exotic properties. A promising approach uses engineered…
