Quantum anomalous Hall effect from intertwined moiré bands
Tingxin Li, Shengwei Jiang, Bowen Shen +8
Electron correlation and topology are two central threads of modern condensed matter physics. Semiconductor moiré materials provide a highly tunable platform for studies of electro…
Spin dynamics slowdown near the antiferromagnetic critical point in atomically thin FePS3
Xiao-Xiao Zhang, Shengwei Jiang, Jinhwan Lee +3
Two-dimensional (2D) magnetic materials have attracted much recent interest with unique properties emerging at the few-layer limit. Beyond the reported impacts on the static magnet…
Tunable exciton-optomechanical coupling in suspended monolayer MoSe2
Hongchao Xie, Shengwei Jiang, Daniel A. Rhodes +3
The strong excitonic effect in monolayer transition metal dichalcogenide (TMD) semiconductors has enabled many fascinating light-matter interaction phenomena. Examples include stro…
Emergence of a noncollinear magnetic state in twisted bilayer CrI3
Yang Xu, Ariana Ray, Yu-Tsun Shao +8
The emergence of two-dimensional (2D) magnetic crystals and moiré engineering has opened the door for devising new magnetic ground states via competing interactions in moiré superl…
Continuous Mott transition in semiconductor moiré superlattices
Tingxin Li, Shengwei Jiang, Lizhong Li +9
The evolution of a Landau Fermi liquid into a nonmagnetic Mott insulator with increasing electronic interactions is one of the most puzzling quantum phase transitions in physics. T…
Giant anisotropic magnetoresistance in Ising superconductor-magnetic insulator tunnel junctions
Kaifei Kang, Shengwei Jiang, Helmuth Berger +5
Superconductivity and magnetism are generally incompatible because of the opposing requirement on electron spin alignment. When combined, they produce a multitude of fascinating ph…
