Extended Data Fig. 4

a) The number of atoms varies less than 5% throughout dynamics. b) Energy in system as a function of time, extracted using the measured momentum space distribution n(k), and integrating ∫dkn(k)k2. The square at t = 0 is the value without an imprint and driving, and circles are after the imprint, measured stroboscopically at the point when the kinetic energy is maximal. c) Contrast of the stripe in x in the central region of the cloud, \(C=n{(x)}_{\max }-n{(x)}_{\min }/n{(x)}_{\max }+n{(x)}_{\min }\), extracted using a sine-fit to mean density distributions of the unperturbed system. d) Wavenumber of the lattice in x, extracted using a Fourier transform of mean density distributions. Standard errors and 1σ fit errors are either shown as the value ± its error or covered by the markers. The data in a, c, and d are derived from data sets of approximately 40 single realizations, while b uses approximately 30 single realizations.
