Interlayer electric multipole Hall effect in twisted multilayers
Chengxin Xiao, Cong Xiao, Dawei Zhai +1
Electrons in layered van der Waals materials possess a layer pseudospin characterizing their wave-function distribution among layers. In twisted structures, this pseudospin forms n…
Spontaneous Symmetry Breaking of Cavity Vacuum and Emergent Gyrotropic Effects in Embedded moiré Superlattices
Zuzhang Lin, Hsun-Chi Chan, Wenqi Yang +4
In an electronic system, spontaneous symmetry breaking can arise from many-body interaction between electrons, leading to degenerate ground states distinguishable by emergent effec…
Extrinsic Contribution to Nonlinear Current Induced Spin Polarization
Ruda Guo, Yue-Xin Huang, Xiaoxin Yang +3
Nonlinear spin polarization occurring in the second order of driving electric current is the dominant source of nonequilibrium magnetization in centrosymmetric or weakly noncentros…
Intrinsic Dipole Hall effect in twisted MoTe: magnetoelectricity and contact-free signatures of topological transitions
Feng-Ren Fan, Cong Xiao, Wang Yao
We discover an intrinsic dipole Hall effect in a variety of magnetic insulating states at integer fillings of twisted MoTe moiré superlattice, including topologically trivial a…
Layer Coherence Origin of Planar Hall Effect: from Charge to Multipole and Valley
Huiyuan Zheng, Dawei Zhai, Cong Xiao +1
We uncover a new origin of the planar Hall effect - as an intrinsic property of layer coherent electrons - that exists even in bilayer and trilayer atomically thin limit. It reform…
Dynamical Chiral Nernst Effect in Twisted Van der Waals Few Layers
Juncheng Li, Dawei Zhai, Cong Xiao +1
The Nernst effect is a fundamental thermoelectric conversion phenomenon that was deemed to be possible only in systems with magnetic field or magnetization. In this work, we propos…
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…
