Theoretical/Computational Studies of High-Temperature Superconductivity from Quantum Magnetism

Abstract

The symmetry of a single Cooper pair in a monolayer of hole-doped or electron-doped iron superconductor was determine at the limit of strong on-site Coulomb repulsion, with only the 3d xz and the 3d yz iron orbitals included. Exact numerical diagonalization that exploited AFRL supercomputers, in addition to meanfield theory, find isotropic pairing on the electron Fermi surface pockets plus isotropic pairing of opposite sign on hole bands buried below the Fermi level. These results potentially account for the high-temperature superconductivity displayed recently by surface layers of iron selenide.
