Influence of the inter-orbital interaction and kinetic terms on superconductivity: a simple two-orbital Hubbard model
Vito Marino, Diego Florez-Ablan, Luca F. Tocchio +2
We investigate a minimal two-orbital Hubbard model with intra- and inter-orbital nearest-neighbor hopping and , as well as intra- and inter-orbital density-density i…

Variational Monte Carlo study of a two-orbital Hubbard model for the iron pnictides
Vito Marino, Gabriele Gatti, Massimo Capone +1
We study a two-orbital Hubbard-Kanamori model, which has been originally proposed for iron-based superconductors, using variational Monte Carlo. We span the nonmagnetic sector at b…
