Real-space identification of distinct magnetic configurations in a candidate d-wave altermagnet
Jin-Cheng Gu, Mingzhe Hu, Ziyin Song +11
Altermagnetism is an emerging class of magnetic order characterized by momentum-dependent spin-split electronic structures despite vanishing net magnetization. Although momentum-sp…
Pronounced orbital-selective electron-electron correlation and electron-phonon coupling in V2Se2O
Mingzhe Hu, Ziyin Song, Jingwen Cheng +16
Orbital-selective many-body effects, in which electrons occupying different orbitals experience distinct interaction strengths, play a crucial role in correlated multiorbital mater…
Spectroscopic signatures of magnetization-induced band renormalization and strong spin-charge-lattice coupling in EuZnAs
Zhiyu Liao, Boxuan Li, Shaohui Yi +9
We report an infrared spectroscopy study of the antiferromagnetic (AFM) insulator EuZnAs over a broad frequency range, spanning temperatures both above and below the AFM tr…
Orbital-selective effect of spin reorientation on the Dirac fermions in a non-charge-ordered kagome ferromagnet FeGe
Rui Lou, Liqin Zhou, Wenhua Song +13
Kagome magnets provide a fascinating platform for the realization of correlated topological quantum phases under various magnetic ground states. However, the effect of the magnetic…
Discovery of a metallic room-temperature d-wave altermagnet KV2Se2O
Bei Jiang, Mingzhe Hu, Jianli Bai +19
Beyond conventional ferromagnetism and antiferromagnetism, altermagnetism is a recently discovered unconventional magnetic phase characterized by time-reversal symmetry breaking an…
Intrinsic second-order topological insulators in two-dimensional polymorphic graphyne with sublattice approximation
Z. J. Chen, S. G. Xu, Z. J. Xie +2
In two dimensions, intrinsic second-order topological insulators (SOTIs) are characterized by topological corner states that emerge at the intersections of distinct edges with reve…
