Variational Monte Carlo for the Hubbard model
Luca F. Tocchio
In these lecture notes, we introduce the variational Monte Carlo method for the Hubbard model. First, we briefly introduce the single-orbital Hubbard model and its multi-orbital ex…
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…
Variational Benchmarks for Quantum Many-Body Problems
Dian Wu, Riccardo Rossi, Filippo Vicentini +30
The continued development of computational approaches to many-body ground-state problems in physics and chemistry calls for a consistent way to assess its overall progress. In this…
