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…
Intertwined superconductivity and orbital selectivity in a three-orbital Hubbard model for the iron pnictides
Vito Marino, Alberto Scazzola, Federico Becca +2
We study a three-orbital Hubbard-Kanamori model relevant for iron-based superconductors using variational wave functions explicitly including spatial correlations and electron pair…
Variational Monte Carlo study of stripes as a function of doping in the Hubbard model
Antonio Lechiara, Vito Marino, Luca F. Tocchio
We perform variational Monte Carlo simulations of the single-band Hubbard model on the square lattice with both nearest () and next-nearest () neighbor hoppings. Our work in…
