Phase-shifted multicomponent spin-charge nematicity in an altermagnet
Christopher Candelora, Siyu Cheng, Muxian Xu +7
The paper reports the observation of a phase‑shifted spin‑charge nematic state in the altermagnet Co0.25NbSe2, where charge and spin nematic components break rotational symmetry wi…
Discovery of parity-violating chiral polar-nematic charge density wave and superconductivity in kagome metals
Xingwei Shi, Geng Li, Zhan Wang +16
Nonmagnetic kagome metals and superconductors AV3Sb5 (A = K, Rb, Cs) host unconventional charge density wave (CDW) and superconducting (SC) phases accompanied by multiple electroni…
Electronic structure of VSb kagome metals
Keyu Zeng, Zhan Wang, Kun Jiang +1
The kagome metals VSb ( K, Cs, Rb) have become a fascinating materials platform following the discovery of many novel quantum states due to the interplay between ele…
Frieze charge-stripes in a correlated kagome superconductor CsCrSb
Siyu Cheng, Keyu Zeng, Yi Liu +4
Kagome metals have developed into a vibrant playground for materials physics, where geometric frustration, electronic correlations and band topology come together to create a varie…
Roton Superconductivity from Loop-Current Chern Metal on the Kagome Lattice
Zhan Wang, Keyu Zeng, Ziqiang Wang
Motivated by the evidence for time-reversal symmetry (TRS) breaking in nonmagnetic kagome metals AV3Sb5, a novel electronic order of persistent orbital loop-current (LC) has been p…
