SUMMARY:Observation of Universal Hall Response in Strongly Interacting Fermions ( Michele Filippone / Seminar / LPT). - 4/04/2023\, 14H
DESCRIPTION:Michele Filippone (CEA Grenoble) \nSeminar LPT\, 4 april 2023\, 14H\, 3R1\, seminar room\, 3rd floor \nSummary : The Hall effect originates from the motion of charged particles in a magnetic field and has deep consequences for the description and characterization of materials\, far beyond the context of condensed matter physics. Understanding the Hall effect in interacting systems still represents a fundamental challenge. Here [1] 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 [2-3]. Our approach and findings open new directions for the quantum simulation of strongly correlated topological states of matter. \n
