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…

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…

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…
