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…
Crossing-Line-Node Semimetals: General Theory and Application to Rare-Earth Trihydrides
Shingo Kobayashi, Youichi Yamakawa, Ai Yamakage +3
Multiple line nodes in energy-band gaps are found in semimetals preserving mirror-reflection symmetry. We classify possible configurations of multiple line nodes with crossing poin…
Line-Node Dirac Semimetal and Topological Insulating Phase in Noncentrosymmetric Pnictides CaAgX (X = P, As)
Ai Yamakage, Youichi Yamakawa, Yukio Tanaka +1
Two noncentrosymmetric ternary pnictides, CaAgP and CaAgAs, are reported as topological line-node semimetals protected solely by mirror-reflection symmetry. The band gap vanishes o…
