Ab Initio Theory of Unconventional Superconductivity

S. Acharya, Casey Eichstaedt, Peyton Cline, Ross Larsen, D. Pashov, Mark van Schilfgaarde

Research output: NREL › Poster

Abstract

This is an overview of the Quasiparticle Self-Consistent GW Approximation (QSGW) with the following: (1) Origins of Superconductivity in FeSe, (2) Properties of YFe2Ge2, (3) Dynamical Mean Field Theory: for strong local correlations, and (4) is TiSe2 an excitonic insulator?
