Direct observation of quadruple spin-texture locking in a 2D d-wave altermagnet
Dan Mu, Bei Jiang, Qingchen Duan +14
Altermagnets combine vanishing net magnetization with nonrelativistic, momentum-dependent spin splitting, offering a new paradigm for spintronics. Spin-crystal symmetry coupling, n…
Heavy-Fermion Behavior and a Tunable Density Wave in a Novel Vanadium-based Mosaic Lattice
Yusen Xiao, Zhibin Qiu, Qingchen Duan +4
The pursuit of geometrically frustrated lattices beyond conventional paradigms remains a central challenge in the design of quantum materials. Herein, we report the discovery of Cs…
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…
Observation of spin-valley locked nodal lines in a quasi-2D altermagnet
Quanxin Hu, Xingkai Cheng, Qingchen Duan +19
The interplay among quantum degrees of freedom-spin, orbital and momentum-has emerged as a fertile ground for realizing magnetic quantum states with transformative potential for el…
Disorder-induced spin excitation continuum and spin-glass ground state in the inverse spinel CuGaO
Zhentao Huang, Zhijun Xu, Shuaiwei Li +18
Spinel-structured compounds serve as prototypical examples of highly frustrated systems, and are promising candidates for realizing the long-sought quantum spin liquid (QSL) state.…
