Direct observation of how the heavy fermion state develops in CeCoIn5
Q. Y. Chen, D. F. Xu, X. H. Niu +19
Heavy fermion materials gain high electronic masses and expand Fermi surfaces when the high-temperature localized f electrons become itinerant and hybridize with the conduction ban…
Bulk and surface electronic structure of trigonal structured PtBi2 studied by angle-resolved photoemission spectroscopy
Q. Yao, Y. P. Du, X. J. Yang +12
PtBi2 with a layered trigonal crystal structure was recently reported to exhibit an unconventional large linear magnetoresistance, while the mechanism involved is still elusive. Us…
Presence of Exotic Electronic Surface States in LaBi and LaSb
X. H. Niu, D. F. Xu, Y. H. Bai +7
Extremely high magnetoresistance (XMR) in the lanthanum monopnictides La ( = Sb, Bi) has recently attracted interest in these compounds as candidate topological materials. Ho…
Highly anisotropic and two-fold symmetric superconducting gap in nematically ordered FeSeS
H. C. Xu, X. H. Niu, D. F. Xu +7
FeSe exhibits a novel ground state in which superconductivity coexists with a nematic order in the absence of any long-range magnetic order. Here we report an angle-resolved photoe…
