DOI: 10.1103/physrevb.102.014502
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.

DOI: 10.1103/physrevlett.119.267001
Abstract: Monolayer FeSe exhibits the highest transition temperature among the iron based superconductors and appears to be fully gapped, seemingly consistent with s-wave superconductivity. Here, we develop a theory for the superconductivity based on coupling to… read more here.
