Stacking-order-dependent electronic properties of MoTe2/WSe2 moiré bilayers
Zhongdong Han, Wenjin Zhao, Eegene Clara Chung +17
Transition metal dichalcogenide (TMD) moiré bilayers have realized a wide range of strongly correlated and topological phenomena. The physics in these materials is often sensitive…
Thermoelectricity of moiré heavy fermions in MoTe2/WSe2 bilayers
Yichi Zhang, Wenjin Zhao, Zhongdong Han +4
Tunable Kondo lattice and heavy fermion physics have been recently reported in moiré materials, but most of the studies have focused on the electrical and magnetic properties. Qua…
Evidence of topological Kondo insulating state in MoTe2/WSe2 moiré bilayers
Zhongdong Han, Yiyu Xia, Zhengchao Xia +6
Topological Kondo insulators (TKIs) are topologically protected insulating states induced not by single-particle band inversions, but by the Kondo interaction between itinerant ele…
Emergence of Chern metal in a moiré Kondo lattice
Wenjin Zhao, Zui Tao, Yichi Zhang +9
A Chern metal is a two-dimensional metallic state of matter carrying chiral edge states. It can emerge as a doped Chern insulator, but theoretical studies have also predicted its e…
Magnetochiral anisotropy on a quantum spin Hall edge
Youjian Chen, Gary Quaresima, Wenjin Zhao +3
We develop a theory of nonlinear low-magnetic-field magnetotransport on a helical edge of a quantum spin Hall insulator due to the edge state coupling to bulk midgap states. We foc…
