Anisotropic superconducting gaps in YNi${}_2$B${}_2$C: A first-principles investigation

Mitsuaki Kawamura, Ryosuke Akashi, Shinji Tsuneyuki

We calculate superconducting gaps and quasiparticle density of states of YNi${}_2$B${}_2$C in the framework of the density functional theory for superconductors to investigate the orig…
