متن کاملQuasiparticle scattering interference in superconducting iron pnictides
Using both two orbital and five orbital models, we investigate the quasiparticle interference QPI patterns in the superconducting SC state of iron-based superconductors. We compare the results for nonmagnetic and magnetic impurities in sign-changed s-wave cos kx · cos ky and sign-unchanged cos kx · cos ky SC states. While the patterns strongly depend on the chosen band structure details, the se...
متن کاملElectronic correlations in the iron pnictides
In correlated metals derived from Mott insulators, the motion of an electron is impeded by Coulomb repulsion due to other electrons. This phenomenon causes a substantial reduction in the electron’s kinetic energy, leading to remarkable experimental manifestations in optical spectroscopy1. The hightransition-temperature (Tc) superconducting cuprates are perhaps the most studied examples of such ...
متن کاملCorrelation effects in the iron pnictides
One of the central questions about the iron pnictides concerns the extent to which their electrons are strongly correlated. Here we address this issue through the phenomenology of the charge transport and dynamics, single-electron excitation spectrum, and magnetic ordering and dynamics. We outline the evidence that the parent compounds, while metallic, have electron interactions that are suffic...
