Catalog of Altermagnetism in Magnetic Wallpaper/Space Groups and Nonsymmorphic Altermagnets
Congcong Le, Fan Cui, Iao-Fai Io +3
Conventional altermagnetism, characterized by compensated collinear spin alignment and spin splitting, exhibits identical spin states at opposite momenta. In this work, we employ a…
Tunable Dirac Semimetals with Higher-order Fermi Arcs in Kagome Lattices PdPbX (X = S, Se)
Simin Nie, Jia Chen, Changming Yue +4
Bulk-boundary correspondence has achieved a great success in the identification of topological states. However, this elegant strategy doesn't apply to the Dirac semimetals (DSMs).…
Topology and symmetry of circular photogalvanic effect in the chiral multifold semimetals: a review
Congcong Le, Yan Sun
The circular photogalvanic effect (CPGE) is the only possible quantized signal in Chiral Weyl and multi-fold semimetals with inversion and mirror symmetries broken. Here, we review…
Giant anomalous Nernst signal in the antiferromagnet YbMnBi2
Yu Pan, Congcong Le, Bin He +6
Searching for a high anomalous Nernst effect (ANE) is crucial for thermoelectric energy conversion applications because the associated unique transverse geometry facilitates module…
Large anomalous Hall effect in the kagome ferromagnet LiMnSn
Dong Chen, Congcong Le, Chenguang Fu +4
Kagome magnets are believed to have numerous exotic physical properties due to the possible interplay between lattice geometry, electron correlation and band topology. Here, we rep…
Observation of the Critical State to Multiple-Type Dirac Semimetal Phases in KMgBi
D. F. Liu, L. Y. W, C. C. Le +21
Dirac semimetals (DSMs) are classified into different phases based on the types of the Dirac fermions. Tuning the transition among different types of the Dirac fermions in one syst…
