Spin nematic liquid crystal and scalar spin chirality in tetragonal lattice YbMnBi
Yaofeng Xie, Sijie Xu, Yu Pan +22
A spin nematic order, analogous to the nematic liquid crystal, characterizes the spontaneous breaking of spin-space rotational symmetry while preserving time-reversal () symmetr…
Topological Lifshitz transition-induced bipolarity of anomalous Nernst effect in kagome magnet YCo3
Sheng Xu, Yue-Yang Wu, Hao-Ran Bai +10
The kagome lattice, renowned for hosting topological band structures and rich magnetic behaviors, offers an exceptional setting to investigate unconventional transport in magnetic…
Fermi surface of Kagome metal CsCrSb observed by laser photoemission microscopy
Hayate Kunitsu, Iori Ishiguro, Natsuki Mitsuishi +7
We investigated the Fermi surface (FS) in the paramagnetic state of Kagome metal CsCrSb by employing a laser photoemission microscopy. We found a circular FS and two hexago…
Evidence for itinerant electron-local moment interaction in Li-doped -MnTe
Tingjun Zhang, Steven J. Gomez Alvarado, Sijie Xu +17
We use inelastic neutron scattering (INS) and angle-resolved photoemission spectroscopy (ARPES) to study the impact of Li doping on the semiconducting altermagnet -MnTe. Introd…
Spin Excitations and Flat Electronic Bands in a Cr-based Kagome Superconductor
Zehao Wang, Yucheng Guo, Hsiao Yu Huang +33
In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs)…
Absence of Acoustic Phonon Anomaly in a Kagome Metal with Short-ranged Structural Modulation
Weiliang Yao, Supeng Liu, Zifan Xu +9
Kagome lattice VSb ( = K, Rb, and Cs) superconductors without magnetism from vanadium -electrons are intriguing because they have a novel charge density wave (CDW)…
