Origin of the Resistive Anisotropy in the Electronic Nematic Phase of BaFe2As2 Revealed by Optical Spectroscopy

We perform, as a function of uniaxial stress, an optical-reflectivity investigation of the representative "parent" ferropnictide BaFe2As2 in a broad spectral range, across the tetragonal-to-orthorhombic phase transition and the onset of the long-range antiferromagnetic (AFM) order. The inf...
