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…
Topological Phase Transition in a Magnetic Weyl Semimetal
D. F. Liu, Q. N. Xu, E. K. Liu +15
Topological Weyl semimetals (TWSs) are exotic crystals possessing emergent relativistic Weyl fermions connected by unique surface Fermi-arcs (SFAs) in their electronic structures.…
Design strong anomalous Hall effect via spin canting in antiferromagnetic nodal line materials
Congcong Le, Claudia Felser, Yan Sun
The interplay between magnetism and topological electronic structure offers a large freedom to design strong anomalous Hall effect (AHE) materials. A nodal line from band inversion…
