AbstractThe coexistence of superfluid and Mott insulator, due to the quadratic confinement potential in current optical lattice experiments, makes the accurate detection of the superfluid-Mott-insulator transition difficult. Studying alternative trapping potentials which are experimentally realizable and have a flatter center, we find that the transition can be better resolved, but at the cost of a more difficult tuning of the particle filling. When mapping out the phase diagram using local probes and the local density approximation we find that the smoother gradient of the parabolic trap is advantageous. © 2008 The American Physical Society.

The ALPS libraries [18] were used for parallelization and the simulations were performed on the Hreidar cluster of ETH Zurich. We thank W. Q. Chen, I. B. Spielman, N. V. Prokof'ev, Henning Moritz, and Tilman Esslinger for useful discussions. We welcome financial support from RGC of HKSAR and the Swiss National Science Foundation.
