Abstract: We analyse the properties of an ultracold atomic cloud trapped in an external doublewell potential with the Bose-Hubbard approximation. We characterize the many-body properties of the system through the study of the single-particle spectral functions, identifying the di erent regimes that the system exhibits for all the possible parameters in this approach.
