Spin-fluctuation-mediated unconventional $d_{xy}$-wave superconductivity in ThFeAsN from first-principles

Guang-Yu Guo, Jau-Wen Liu, Mitsuaki Kawamura

Superconducting (SC) pairing mechanism, origin of high $T_c$ and symmetry of SC order parameter in Fe-based superconductors are among the important unsolved problems in condensed m…
