Fermi surface and superconducting properties in Rashba-type and chiral-structure compounds

prof. dr Yoshichika Onuki

University of the Ryukyus, Okinawa, Japan

Crystals generally possess mirror symmetry in the crystal structure. Some compounds, however, crystallize in non-centrosymmetric structures. Typical examples have the so-called Rashba-type and chiral structures. In these crystal structures an antisymmetric spin-orbit interaction lifts not only the charge degeneracy but also the spin degeneracy of an electron. Here we present the Fermi surface and superconducting properties of CeIrSi₃ with the Rashba-type tetragonal structure, and the Fermi surface properties of TaSi₂, NbSi₂, and VSi₂ with the hexagonal chiral structure.
