Quantum gas microscopy of the Fermi-Hubbard model in optical superlattices

In the past few years, quantum gas microscopy has proven to be a valuable tool for the experimental exploration of the low-energy quantum many-body states of the Fermi-Hubbard model. More recently, a number of experiments have shifted their interest towards lattice geometries which go beyond the simple square lattice, extending the scope of quantum simulation towards more exotic states. Here, I will report report on our recent implementation of bichromatic optical superlattices in our ⁶Li quantum gas microscope. The phase stability and tunability granted by our design provide the necessary tools to implement novel cooling protocols and preparation techniques in tailored geometries. In combination with the single-site spin and density resolution of our apparatus, such superlattice-based protocols open the way towards the exploration of the pairing mechanisms at play in the low energy doped Fermi-Hubbard model.
