Interaction-resistant metals in multicomponent Fermi systems
Andrea Richaud, Matteo Ferraretto, Massimo Capone
We analyze two different fermionic systems that defy Mott localization showing a metallic ground state at integer filling and very large Coulomb repulsion. The first is a multiorbi…

Effects of long range hopping in the Bose-Hubbard model
M. Ferraretto, L. Salasnich
We investigate the effects of an extended Bose-Hubbard model with a long range hopping term on the Mott insulator-superfluid quantum phase transition. We consider the effects of a…
