Abstract:	The article discusses physics research regarding anisotropic energy gaps of iron (Fe)-based superconductivity from intraband quasiparticle interference in the complex compound lithium iron arsenide (LiFeAs). Topics include the behavior of typical FeAs-based materials, the research team's use of intraband Bogoliubov quasiparticle scattering interference (QPI) techniques to determine anisotropic superconducting energy gaps such materials, and the team's identification of the anisotropy, magnitude, and relative orientations of the superconducting energy gaps of three hole-like bands assigned as γ, α2, and α1.
