Comment on "Nematic Electronic Structure in the "Parent" State of the Iron-Based Superconductor Ca(Fe1-xCox)2As2"

Chuang et al (Reports, 8th of January 2010, p. 181)1 report quasiparticle interference (QPI) imaging that shows pronounced C2 asymmetry. They interpreted this result as indication of an electronic nematic phase with an electron band dispersive only along the b-axis of this orthorhombic material. We...

Summary:Chuang et al (Reports, 8th of January 2010, p. 181)1 report quasiparticle interference (QPI) imaging that shows pronounced C2 asymmetry. They interpreted this result as indication of an electronic nematic phase with an electron band dispersive only along the b-axis of this orthorhombic material. We argue that this asymmetry is consistent with the underlying long range magnetic order and that LDA electronic structure provides a better description of the QPI images than the 1D band structure conjectured by Chuang et al.
