From chiral d-wave to nodal line superconductivity in the harmonic honeycomb lattices

Johann Schmidt, Adrien Bouhon, Annica Black-Schaffer

Motivated by the recent realization of the three-dimensional hyperhoneycomb and stripyhoneycomb lattices in lithium iridate (Li${}_2$IrO${}_3$), we study the possible spin-singlet supe…
