Quasiparticle Interference and Symmetry of Superconducting Order Parameter in Strongly Electron-Doped Iron-based Superconductors

Jakob Böker, Pavel A. Volkov, Peter J. Hirschfeld +1

Motivated by recent experimental reports of significant spin-orbit coupling (SOC) and a sign-changing order-parameter in the Li${}_{1-x}$Fe${}_x$(OHFe)${}_{1-y}$Zn${}_y$Se superconductor w…
