Understanding the Hall effect in interacting systems still represents a fundamental challenge. Here <strong>[1]<\/strong> we directly observe the buildup of the Hall response in an interacting quantum system by exploiting controllable quench dynamics in an atomic quantum simulator, see Figure 1. By tracking the motion of ultracold fermions in a two-leg ribbon threaded by an artificial magnetic field, we measure the Hall response as a function of synthetic tunnelling and atomic interactions. We unveil an interaction-independent universal behaviour above an interaction threshold, in clear agreement with theoretical analyses <strong>[2-3]<\/strong>. Our approach and findings open new directions for the quantum simulation of strongly correlated topological states of matter.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<div class=\"leaflet-map WPLeafletMap\" style=\"height:300px;
