Fig. 3: Interaction-induced localization.
a Contrast of the interference pattern after loading the lattice at different as. The green dot-dashed (black solid) line represents the result of the 1D discrete model (3D extended Gross-Pitaevskii equation, eGPE) multiplied by 0.7. The insets show the respective density distributions along z of the 1D discrete model (bars) and 3D eGPE (lines) and corresponding experimental averaged interference patterns after TOF expansion (1,2). The statistical uncertainties on the scattering length is smaller than the symbols size. b Dynamic evolution of the contrast quenching back (filled circles) or holding as (open circles); see text. The error bars represent the standard error on the mean over 4–6 repetitions.
