The magnetization and lifetimes of atoms in gray optical lattices exhibit modulations as functions of an applied B field that are attributed to tunneling resonances between neighboring lattice wells. Expanding on previous observations, we show how these modulations depend on well depth, and we derive spin temperatures for the system. A band-structure-based model and quantum Monte Carlo wave-function simulations are used to explain these results. We predict subrecoil structures in the velocity distributions; these structures undergo systematic variations when the applied magnetic field is varied. Dramatically different behaviors for bosonic and fermionic spin systems are found and explained.

  21. The tunneling frequency actually depends on quasi-momentum q. Experimental observations of the tunneling, as explained in Ref. 12, yield a frequency that corresponds to the maximum band splitting. In Fig. 3(c) we show the maximum band splittings at the centers of the respective tunneling resonances.
