Quantum gas microscopy has revolutionized quantum simulation with ultracold atoms in optical lattices. So far, it has mostly been applied in the context of the “plain-vanilla” Hubbard model on the square lattice relevant to the high-temperature superconducting cuprates. In this talk, I will report on the microscopy of correlated systems with new ingredients: frustration and dipolar interactions. Our quantum simulations of triangular Hubbard systems have revealed the existence of a “high-temperature” magnetic polaron that emerges due to kinetic frustration in lightly doped systems. This is closely related to very recent observations of kinetic magnetism in Moiré materials and may provide microscopic insights into them. In another line of experiments, our quantum simulations with polar molecules pinned in an optical lattice have allowed us to explore tunable models of non-equilibrium quantum magnets.
