The role of orbital nesting in the superconductivity of Iron-based Superconductors
R. Fernández-Martin, M. J. Calderón, L. Fanfarillo +1
We analyze the magnetic excitations and the spin-mediated superconductivity in iron-based superconductors within a low-energy model that operates in the band basis but fully incorp…
Magnetic interactions in iron superconductors: A review
E. Bascones, B. Valenzuela, M. J. Calderon
High temperature superconductivity in iron pnictides and chalcogenides emerges when a magnetic phase is suppressed. The multi-orbital character and the strength of correlations und…
Correlation, doping and interband effects on the optical conductivity of iron superconductors
M. J. Calderón, L. de' Medici, B. Valenzuela +1
Electronic interactions in multiorbital systems lead to non-trivial features in the optical spectrum. In iron superconductors the Drude weight is strongly suppressed with hole-dopi…
Coupling of the A_{1g} As-phonon to magnetism in iron pnictides
N. A. García-Martínez, B. Valenzuela, S. Ciuchi +3
Charge, spin and lattice degrees of freedom are strongly entangled in iron superconductors. A neat consequence of this entanglement is the behavior of the A_{1g} As-phonon resonanc…
Magnetic interactions in iron superconductors studied with a five-orbital model within the Hartree-Fock and Heisenberg approximations
M. J. Calderon, G. Leon, B. Valenzuela +1
We have analyzed the magnetic interactions of a five orbital model for iron superconductors treated both within Hartree-Fock and Heisenberg approximations. We have found that the e…
Low magnetization and anisotropy in the antiferromagnetic state of undoped iron pnictides
E. Bascones, M. J. Calderon, B. Valenzuela
We examine the magnetic phase diagram of iron pnictides using a five band model. For the intermediate values of the interaction expected to hold in the iron pnictides, we find a me…
