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…
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…
Quantum oscillations between excitonic and quantum spin Hall insulators in moiré WSe2
Zhongdong Han, Yiyu Xia, Kenji Watanabe +3
Quantum spin Hall insulators (QSHIs) and excitonic insulators (EIs) are prototypical topological and correlated states of matter, respectively. The topological phase transition bet…
Simulating high-temperature superconductivity in moiré WSe2
Yiyu Xia, Zhongdong Han, Jiacheng Zhu +6
The emergence of high transition temperature (Tc) superconductivity in strongly correlated materials remains a major unsolved problem in physics. High-Tc materials, such as cuprate…
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…
Correlated states controlled by tunable van Hove singularity in moiré WSe2
Patrick Knüppel, Jiacheng Zhu, Yiyu Xia +7
Twisted bilayers of transition metal dichalcogenide semiconductors have enabled the discovery of superconductivity, ferromagnetism, correlated insulators and a series of new topolo…
Unconventional superconductivity in twisted bilayer WSe2
Yiyu Xia, Zhongdong Han, Kenji Watanabe +3
Moiré materials have enabled the realization of flat electron bands and quantum phases that are driven by strong correlations associated with flat bands. Superconductivity has been…
