Microscopic studies of doped cold-atom Fermi-Hubbard antiferromagnets

The experimental platform of ultracold fermionic atoms in optical lattices offers new perspectives for studying the physics of strongly correlated materials. We use this platform to implement the Fermi-Hubbard model, a paradigmatic model thought to capture the physics of high-temperature superconductivity, the pseudogap, and other phenomena containing longstanding open questions. The additional tool of quantum gas microscopy enables site-resolved readout and access to projections of the many-body wavefunction in the Fock basis. I will report on our most recent studies of doped antiferromagnets, where there is no universally agreed-upon mechanism for the interplay between hole motion and antiferromagnetic order.
