We use Bloch oscillations to evaluate the role played by the different interaction terms, and in particular by the quantum fluctuations. We additionally observe a transition&#8211;driven by interactions&#8211;to a state localized to a single lattice plane. To benchmark our results, we developed a discrete one-dimensional extended Gross-Pitaevskii theory. This model is in quantitative agreement with the experiment, additionally revealing, in our parameter regime, the existence of many different phases: macrodroplets occupying single or many lattice sites and two-dimensional bright solitons.\r\n<br>\r\n<br>\r\nSee the open access paper here:\r\n<a href=\"https:\/\/www.nature.com\/articles\/s42005-022-01009-8\">Commun.
