Abstract: We present a novel method for embedding spin and charge fluctuations in an anisotropic, multiband, and full-bandwidth Eliashberg treatment of superconductivity. Our analytical framework, based on the random phase approximation, allows for a self-consistent calculation… read more here.

Abstract: The existence of orbital-dependent electronic correlations has been recognized as an essential ingredient to describe the physics of iron-based superconductors. NaFeAs, a parent compound of iron-based superconductors, exhibits a tetragonal-to-orthorhombic lattice distortion below ${T}_{s}\ensuremath{\approx}60$ K,… read more here.
