Extended strange metal and superconductivity in partially filled moiré Hubbard bands
Yiyu Xia, Yichi Zhang, Zhongdong Han +7
Moiré semiconductors provide a physical realization of the Hubbard model. Bandwidth-tuned Mott transitions and complex phase diagrams mimicking those of high-temperature supercondu…
Autonomous Quantum Transport Measurements of 2D Semiconductors by an AI Agent
Brandon Bauer, Matthew Whalen, Kenji Watanabe +4
Artificial-intelligence (AI) agents are beginning to enter experimental laboratories, automating experiments and accelerating scientific discovery. Herein, we introduce an AI-drive…
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…
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…
Emergence of ferromagnetism at the onset of moiré Kondo breakdown
Wenjin Zhao, Bowen Shen, Zui Tao +9
The interaction of a lattice of localized magnetic moments with a sea of conduction electrons in Kondo lattice models induces rich quantum phases of matter, such as Fermi liquids w…
Observation of spin polarons in a frustrated moiré Hubbard system
Zui Tao, Wenjin Zhao, Bowen Shen +5
The electron's kinetic energy plays a pivotal role in magnetism. While virtual electron hopping promotes antiferromagnetism in an insulator, the real process usually favors ferroma…
Giant spin Hall effect in AB-stacked MoTe2/WSe2 bilayers
Zui Tao, Bowen Shen, Wenjin Zhao +9
The spin Hall effect (SHE), in which electrical current generates transverse spin current, plays an important role in spintronics for the generation and manipulation of spin-polari…
Magnetotransport on quantum spin Hall edge coupled to bulk midgap states
Youjian Chen, Wenjin Zhao, Elliott Runburg +2
We consider magnetotransport on a helical edge of a quantum spin Hall insulator, in the presence of bulk midgap states ``side-coupled" to the edge. In the presence of a magnetic fi…
Gate-tunable heavy fermions in a moiré Kondo lattice
Wenjin Zhao, Bowen Shen, Zui Tao +6
The Kondo lattice, describing a matrix of local magnetic moments coupled via spin-exchange interactions to itinerant conduction electrons, is a prototype of strongly correlated qua…
Valley-coherent quantum anomalous Hall state in AB-stacked MoTe2/WSe2 bilayers
Zui Tao, Bowen Shen, Shengwei Jiang +11
Moiré materials provide fertile ground for the correlated and topological quantum phenomena. Among them, the quantum anomalous Hall (QAH) effect, in which the Hall resistance is qu…
Realization of the Haldane Chern insulator in a moiré lattice
Wenjin Zhao, Kaifei Kang, Lizhong Li +7
The Chern insulator displays a quantized Hall effect without Landau levels. In a landmark paper in 1988, Haldane showed that a Chern insulator could be realized through complex nex…
Evidence for equilibrium excitons and exciton condensation in monolayer WTe2
Bosong Sun, Wenjin Zhao, Tauno Palomaki +14
A single monolayer of the layered semimetal WTe2 behaves as a two-dimensional topological insulator, with helical conducting edge modes surrounding a bulk state that becomes insula…
