Realization of a Fractional Quantum Hall State with Ultracold Atoms

dc.description.abstract
Fractional quantum Hall states embody emblematic instances of strongly correlated topological matter, where the interplay of magnetic fields and interactions gives rise to exotic properties including fractionally charged quasi-particles, long-ranged entanglement, and anyonic exchange statistics. Here, we report on the realization of a fractional quantum Hall (FQH) state with ultra-cold atoms in an optical lattice. The state is a lattice version of a bosonic 𝜈 = 1/2 Laughlin state with two particles on sixteen sites. We observe a suppression of two-body interactions, we find a distinctive vortex structure in the density correlations, and we measure a fractional Hall conductivity of 𝜎H/𝜎0 = 0.6(2) via the bulk response to a magnetic perturbation. Our work provides a starting point for exploring highly entangled topological matter with ultracold atoms.
