Abstract: We calculate superconducting gaps and quasiparticle density of states of ${\mathrm{YNi}}_{2}{\mathrm{B}}_{2}\mathrm{C}$ in the framework of the density functional theory for superconductors to investigate the origin of highly anisotropic superconducting gaps in this material. Calculated phonon… read more here.

Abstract: In many unconventional superconductors, the pairing of electrons is driven by the repulsive interaction, which leads to the sign reversal of superconducting gaps along the Fermi surfaces (FS) or between them. However, to measure this… read more here.
