30. Naturally, the methods without the extra potential of Eq. (8) should be used when one wants to calculate the thermodynamical properties of an atomic cloud in the whole lattice. These methods are already well-known; the purpose here is to give a new method for calculation of the collision rate.
31. See Ref. 18 for the details of the jump operators that are used in our implementation of the method.
32. It takes a finite length of time before the atoms begin to accumulate in the accumulation region. This is due to the finite distance between the initial lattice site and the accumulation region; see Fig. 1. Thus there is a small time delay in the simulation before the accumulation curve in Fig. 2 begins to increase and achieves nonzero values. We emphasize that it is only the slope β of the accumulation curve that is relevant for the collision-rate calculation here.
33. This is in agreement with the result given in Ref. 10 where the collisions are also a measure of atomic transport in a lattice.
