Analytical mean-field approach to the phase-diagram of ultracold bosons in optical superlattices
P. Buonsante, V. Penna, A. Vezzani
We report a multiple-site mean-field analysis of the zero-temperature phase diagram for ultracold bosons in realistic optical superlattices. The system of interacting bosons is des…
From the superfluid to the Mott regime and back: triggering a non-trivial dynamics in an array of coupled condensates
P Buonsante, R Franzosi, V Penna
We consider a system formed by an array of Bose-Einstein condensates trapped in a harmonic potential with a superimposed periodic optical potential. Starting from the boson field H…
Persistence of mean-field features in the energy spectrum of small arrays of Bose-Einstein condensates
P. Buonsante, R. Franzosi, V. Penna
The Bose-Hubbard Hamiltonian capturing the essential physics of the arrays of interacting Bose-Einstein condensates is addressed, focusing on arrays consisting of two (dimer) and t…
Dynamics of twin-condensate configurations in an open chain of three Bose-Einstein condensates
P. Buonsante, R. Franzosi, V. Penna
The dynamics of a mean-field model of three coupled condensates is studied for initial states characterized by twin condensates. Condensates occupy an open three-well chain, where…
