Coupled Spin-Density-Wave and Bond-Order Driven Metal-Insulator Transition in Altermagnetic CsCrSO
Chenchao Xu, Wansheng Bai, Guo-Xiang Zhi +4
The paper identifies a metal‑insulator transition in CsCr₂S₂O that arises from a bond‑order instability coupled to a secondary spin‑density wave, enabled by pre‑existing altermagne…
Antiferromagnetic Dimers in the Parent Phase of a Correlated Kagome Superconductor
Yifan Wang, Chenchao Xu, Yi Liu +18
Kagome metals are prone to charge-density wave (CDW), magnetic, and superconducting phases, with their flat electronic band conducive for correlated physics. In contrast to the wea…
Soft Phonon Charge-Density Wave Formation in the Kagome Metal KVSb
Yifan Wang, Chenchao Xu, Zhimian Wu +11
A range of of unusual emergent behaviors have been reported in the charge-density wave (CDW) state of the VSb (K, Rb, Cs) kagome metals, including a CDW formation p…
Controlling an altermagnetic spin density wave in the kagome magnet CsCr3Sb5
Zihao Huang, Chenchao Xu, Yande Que +8
The interplay of charge and spin orders lies at the heart of correlated electron physics and plays a critical role in the emergence of unconventional quantum phases. Kagome magnets…
Anomalous Nernst Effect and Its Implications for Time-Reversal Symmetry Breaking in Kagome Metal ScV6Sn6
Yazhou Li, Saizheng Cao, Jiaxing Liao +10
The nonmagnetic kagome metal ScV6Sn6 displays an unconventional charge order (CO) accompanied by signatures of an anomalous Hall effect, hidden magnetism, and multiple lattice inst…
Altermagnetic Ground State in Distorted Kagome Metal CsCrSb
Chenchao Xu, Siqi Wu, Guo-Xiang Zhi +5
The CsCrSb exhibits superconductivity in close proximity to a density-wave (DW) like ground state at ambient pressure\cite{Liu:2024aa}, however details of the DW is still e…
