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…
Spontaneous emergence of altermagnetism in the single-orbital extended Hubbard model
Jin-Wei Dong, Yu-Han Lin, Ruiqing Fu +4
Altermagnetism (AM), the recently discovered third class of collinear magnetic order, is characterized by non-relativistic momentum-dependent spin-split electronic structure with c…
Distinct lattice and charge excitations in AV3Sb5 kagome superconductors
