25. The relatively high trap frequency that we consider is guided solely by numerical considerations: an atom in the lowest trap level that experiences a recoil □ kL =2π□/795□nm along either of the axes is excited to a trap level nr ≈ □ k2 /2M ωt, or nr ≈ 103 for typical trap frequencies (ωt =10π□rad/s in). Our choice of ωt reduces nr by two orders of magnitude, rendering the problem computationally significantly more tractable.
26. The rapid rise at the tail end of that curve is a consequence of the finite number of trap levels in the simulations. Since the population of high levels remains low at all times this artifact does not significantly affect our conclusions.
