Coupled Spin-Density-Wave and Bond-Order Driven Metal-Insulator Transition in Altermagnetic CsCrSO
Chenchao Xu, Wansheng Bai, Guo-Xiang Zhi +4
A metal-insulator transition (MIT) driven by bond order (BO) coupled with a secondary spin-density wave (SDW) is identified in CsCrSO. Such coupling is enabled as a result…
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…
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…
Anisotropic transport properties and topological Hall effect in the annealed kagome antiferromagnet FeGe
Jiajun Ma, Chenfei Shi, Yantao Cao +11
Electron correlation often gives birth to various orders in quantum materials. Recently, a strongly correlated kagome antiferromagnet FeGe is discovered to undergo a charge density…
Competing charge-density wave instabilities in the kagome metal ScVSn
Saizheng Cao, Chenchao Xu, Hiroshi Fukui +5
Owing to its unique geometry, the kagome lattice hosts various many-body quantum states including frustrated magnetism, superconductivity, and charge-density waves (CDWs), with int…
Pressure-induced concomitant topological and metal-insulator quantum phase transitions in CePdBi
Chenchao Xu, Chao Cao, Jian-Xin Zhu
The electronic property and magnetic susceptibility of CePdBi were systemically investigated from 18 K to 290 K for varying values of cell-volume using dynamic mean-fie…
Doping dependence of electronic structure of infinite-layer NdNiO2
Zhao Liu, Chenchao Xu, Chao Cao +3
We investigate the electronic structure of nickelate superconductor NdNiO2 upon hole doping, by means of density-functional theory and dynamical mean-field theory. We demonstrate t…
