Emergence of a symmetry-broken Chern insulator near a moiré Kondo breakdown
Wanghao Tian, Bowen Shen, Lizhong Li +14
Moiré semiconductors built on angle-aligned transition metal dichalcogenide (TMD) heterobilayers provide a physical realization of the Kondo lattice model, in which one TMD layer…
Hydrostatic Pressure-enhanced correlated magnetism and Chern insulator in moir'e WSe2
Pengfei Jiao, Chenghao Qian, Ning Mao +24
Moiré semiconductors offer flat bands where Coulomb interactions and band topology intertwine, while interlayer coupling plays a central role in forming the moiré potential. Howe…
Quantum-geometry-enabled Landau-Zener tunneling in singular flat bands
Xuanyu Long, Feng Liu
Flat-band materials have attracted substantial interest for their intriguing quantum geometric effects. Here we investigate how singular flat bands (SFBs) respond to a static, unif…
Mechanical sensing of metamagnetic tricriticality in two-dimensional CrI3
Feng Liu, Jiayong Xiao, Shengwei Jiang +2
Layered Ising metamagnets are antiferromagnetic (AF) materials consisting of monolayer Ising ferromagnets coupled to each other via interlayer AF interactions. They exhibit rich ma…
Superconductivity in non-centrosymmetric rhombohedral NbSe2
Zhengxian Li, Xiaoyu Shen, Kai Liu +14
Crystal stacking offers a powerful yet underexplored route to engineer symmetry in layered superconductors. Here we report superconductivity in rhombohedral-stacked NbSe2 (3R-NbSe2…
From fractional Chern insulators to topological electronic crystals in moiré MoTe2: quantum geometry tuning via remote layer
Feng Liu, Fan Xu, Cheng Xu +18
The quantum geometry of Bloch wavefunctions,encoded in the Berry curvature and quantum metric, is believed to be a decisive ingredient in stabilizing fractional quantum anomalous H…
