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…
Observation of Resonance of Kagome Flat Band Doublet
Renjie Zhang, Bei Jiang, Xiangqi Liu +19
The interplay between local and itinerant electrons underpins many correlated and topological quantum states. Kagome lattices provide an ideal platform by hosting both flat (locali…
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…
Novel coupling between charge order and time-reversal-symmetry-breaking superconductivity
Quanxin Hu, Lingfeng Zhang, Yu Zheng +9
The interplay between charge-density waves (CDWs), which break translational symmetry, and spatially homogeneous superconductivity, which breaks global U(1) gauge symmetry, can giv…
Large superconducting diode effect driven by edge states in twisted iron-chalcogenide Josephson junctions
Xiangyu Zeng, Renjie Zhang, Guoliang Guo +10
The superconducting diode effect (SDE)-the unidirectional, dissipationless flow of supercurrent-is a critical element for future superconducting electronics. Achieving high efficie…
