Probing Quantum Hall States at the Single Atom Level – QHASAL

Submission summary

We propose a new route to realize correlated quantum Hall states and probe directly their spatial distribution with single atom resolution. Our strategy is to set ultracold gases in rotation, which allows to mimic the effect of the Lorentz force on electrons despite the electrical neutrality of atoms. We will combine, for the first time, this well-established method with three ingredients: (i) the use of fermionic atoms (ii) the recently developed single-atom imaging and (iii) the use of a Feshbach resonance that allows to dynamically tune the strength of the inter-atomic interactions. These combined ingredients will allow us to circumvent the limitations encountered in previous attempts with rotating Bose gases and reach the correlated quantum Hall regime.
