High-repetition-rate quantum gas microscope for simulating the Fermi Hubbard model

Ultracold fermionic systems have emerged as a leading platform for studying strongly correlated quantum matter, offering direct access to regimes that challenge both classical numerical methods and qubit-based architectures. Here, we present recent results from our fermionic quantum gas microscope optimized for fast data acquisition, enabled by a novel, on-site, rapid evaporative cooling in a deep optical lattice. Reservoir engineering can be used to further reduce the entropy of a region of interest, which is subsequently thermally isolated. The resulting product state can then be transformed into a bilayer, strongly correlated system by means of an optical superlattice. We further aim to employ a programmable optical lattice to dynamically tune next-nearest-neighbor hopping, which is predicted to give rise to superconducting correlations. Combined with spin-resolved imaging, this platform provides a versatile route toward the controlled preparation and detection of exotic phases of the Fermi-Hubbard model.
