    • Our simulations use a 8th-9th order adaptive stepsize Runge-Kutta Fehlberg method. The cutoff energy Ecut was typically taken as the van der Waals energy of a pair of atoms at a distance rcut=rb0/2, Nmax was about 4-6. For case (i), we used rcut=0.38rb0. None of the results presented changed upon moderate variation of Ecut, Nmax, the time-step tolerance, or the cubic box dimension L.

    • To extrapolate, we simply scale the total atom number from 84 to 107. This assumes that the simulated cube gives a representative sample of the dynamics of a large homogenous atomic gas.
