Observation of Dirac-like energy band and ring-torus Fermi surface associated with the nodal line in topological insulator CaAgAs
D. Takane, K. Nakayama, S. Souma +10
One of key challenges in current material research is to search for new topological materials with inverted bulk-band structure. In topological insulators, the band inversion cause…
Three-dimensional band structure of LaSb and CeSb:Absence of band inversion
H. Oinuma, S. Souma, D. Takane +9
We have performed angle-resolved photoemission spectroscopy (ARPES) of LaSb and CeSb, a candidate of topological insulator. Using soft-x-ray photons, we have accurately determined…
Emergence of quantum critical behavior in metallic quantum-well states of strongly correlated oxides
Masaki Kobayashi, Kohei Yoshimatsu, Taichi Mitsuhashi +7
Controlling quantum critical phenomena in strongly correlated electron systems, which emerge in the neighborhood of a quantum phase transition, is a major challenge in modern conde…
