Symplectic connection third-order Hall effect in a room-temperature ferromagnet
Yu Cao, Xukun Feng, Yiming Guo +18
Third-order nonlinear Hall effects (THE) have recently attracted considerable experimental interest as powerful probes for quantum geometric properties in emergent quantum material…
Optimized growth of large-size, high quality single crystals enabling clear quantum oscillations in electrical transport
Hong Du, Yu Cao, Jiahao Chen +3
Quantum oscillation with nontrivial Berry phase is one of the characteristics of topological materials. As a Dirac semimetal candidate, zirconium pentatelluride () s…
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…
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…
Coexistence of unconventional spin-orbit torque and in-plane Hall effect in a single ferromagnetic layer
Jiaxin Chen, Hongsheng Zheng, Hongliang Chen +18
The symmetry of a material fundamentally governs its spin transport properties. While unconventional spin transport phenomena have been predominantly explored in low-symmetry syste…
