15. The x-axis in Fig. 2(b) is not directly the energy in the potential because our trap bottom exhibits long term drifts. As the different data points were taken in time order a linear drift leads to a scaling of the energy axis which can be compensated by leaving the temperature in the fitting procedure as a free parameter.
16. For this gradient, the required lattice height for a localization within one lattice site and a simultaneous suppression of Zener tunnelling is s > 10.
17. The asymmetry in the population of the two clouds rises from a small horizontal tilt of our magnetic trap with respect to gravity. As a consequence, the potential minimum does not coincide with the magnetic field minimum
