Effect of Crystal-Field Splitting and Inter-Band Hybridization on the Metal-Insulator Transitions of Strongly Correlated Systems
Alexander I. Poteryaev, Michel Ferrero, Antoine Georges +1
We investigate a quarter-filled two-band Hubbard model involving a crystal-field splitting, which lifts the orbital degeneracy as well as an inter-orbital hopping (inter-band hybri…
Crystallization of the resonating valence bond liquid as vortex condensation
Arnaud Ralko, Michel Ferrero, Federico Becca +2
We show that the liquid-to-crystal quantum phase transition in the Rokhsar--Kivelson dimer model on the two-dimensional triangular lattice occurs as a condensation of vortex-like e…
Dynamical behavior across the Mott transition of two bands with different bandwidths
Michel Ferrero, Federico Becca, Michele Fabrizio +1
We investigate the role of the bandwidth difference in the Mott metal-insulator transition of a two-band Hubbard model in the limit of infinite dimensions, by means of a Gutzwiller…
