Extended Bose-Hubbard model for two-leg ladder systems in artificial magnetic fields
Extended Bose-Hubbard model for two-leg ladder systems in artificial magnetic fields
We investigate the ground state properties of ultracold atoms with long range interactions trapped in a two leg ladder configuration in the presence of an artificial magnetic field. Using a Gross-Pitaevskii approach and a mean field Gutzwiller variational method, we explore both the weakly interacting and strongly interacting regime, respectively. …
