| الوصف: | We discuss how to analyze the optical conductivity and Raman spectra of multiorbital systems using the velocity and the Raman vertices in a similar way Raman vertices were used to disentangle nodal and antinodal regions in cuprates. We apply this method to iron superconductors in the magnetic and nonmagnetic states, studied at the mean-field level. We find that the anisotropy in the optical conductivity at low frequencies reflects the difference between the magnetic gaps at the X and Y electron pockets. Both gaps are sampled by Raman spectroscopy. We also show that the Drude weight anisotropy in the magnetic state is sensitive to small changes in the lattice structure. © 2013 American Physical Society. ; We acknowledge funding from Ministerio de Economía y Competitividad through Grants No. FIS 2008-00124, No. FIS 2009-08744, No. FIS 2011-29689, and from CSIC through Grants No. PIE-200960I033 and No. PIE-200960I180. ; Peer Reviewed |
