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…
Generalized Fermion Doubling Theorems: Classification of 2D Nodal Systems in Terms of Wallpaper Groups
Congcong Le, Zhesen Yang, Fan Cui +2
The Nielsen-Ninomiya Theorem has set up a ground rule for the minimal number of the topological points in a Brillouin zone. Notably, in the 2D Brillouin zone, chiral symmetry and s…
Coexistence of ferromagnetism, antiferromagnetism, and superconductivity in magnetically anisotropic (Eu,La)FeAs2
Jia Yu, Congcong Le, Zhiwei Li +8
Materials with exceptional magnetism and superconductivity usually conceive emergent physical phenomena. Here, we investigate the physical properties of the (Eu,La)FeAs2 system wit…
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…
