Resumen
We investigate the access of Josephson and Self-Trapping dynamical regimes on Bose-Einstein condensates confined by a rotating multiwell trap. Manipulation of the rotation allows us to tune the hopping phase among neighbouring sites within a two-mode model, and permits us to demonstrate that it is possible to dynamically connect qualitatively different regimes. For a sudden increase of the rotation frequency, we find that it is possible to reach both Josephson and Self-Trapping regimes starting from broad range of initial states. Conversely, slow changes in the rotation frequency restrict this possibility to initial states very close to Josephson-Self-Trapping regime separatrix. These findings are corroborated by numerical simulations of the three-dimensional Gross-Pitaevskii equation.
