Competing Pairing Symmetries in a Generalized Two-Orbital Model for the Pnictides
Andrew Nicholson, Weihao Ge, Xiaotian Zhang +6
We introduce and study an extended "t-U-J" two-orbital model for the pnictides that includes Heisenberg terms deduced from the strong coupling expansion. Including these J terms ex…

On interband pairing in multiorbital systems
Adriana Moreo, Maria Daghofer, Andrew Nicholson +1
The discovery of high- superconductivity in the pnictides, materials with a Fermi surface determined by several bands, highlights the need to understand how superconductivity…
