Detecting sign-changing superconducting gap in LiFeAs using quasiparticle interference
D. Altenfeld, P. J. Hirschfeld, I. I. Mazin +1
Using a realistic ten-orbital tight-binding model Hamiltonian fitted to the angle-resolved photoemission (ARPES) data on LiFeAs, we analyze the temperature, frequency, and momentum…

Experimental Demonstration of the Sign Reversal of the Order Parameter in (Li1-xFex)OHFe1-yZnySe
Zengyi Du, Xiong Yang, Dustin Altenfeld +8
Iron pnictides are the only known family of unconventional high-temperature superconductors besides cuprates. Until recently, it was widely accepted that superconductivity is spin-…

Robust determination of superconducting gap sign changes via quasiparticle interference
P. J. Hirschfeld, D. Altenfeld, I. Eremin +1
Phase-sensitive measurements of the superconducting gap in Fe-based superconductors have proven more difficult than originally anticipated. While quasiparticle interference (QPI) m…
