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…
Enhanced coherence and layer-selective charge order in a trilayer cuprate superconductor
S. Smit, M. Bluschke, P. Moen +25
Trilayer cuprates hold the record for the highest superconducting critical temperatures (), yet the underlying mechanism remains elusive. Using time- and angle-resolv…
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…
Superconductor-Insulator transition in a two-orbital attractive Hubbard model with Hund's exchange
Laura Torchia, Massimo Capone
We study a two-orbital attractive Hubbard model with a repulsive Hund's exchange coupling as an idealized model for a two-band superconductor. This framework is motivated by a…
