Microscopic studies of doped cold-atom Fermi-Hubbard antiferromagnets

Ultracold fermions in optical lattices offers new perspectives for studying the physics of strongly correlated materials. We use this experimental 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. We report on our most recent studies of doped antiferromagnets in 2D, where there is no universally agreed-upon mechanism describing the interplay between hole motion and antiferromagnetic order.
