We present the progress towards constructing a dipolar quantum gas microscope using dysprosium atoms. This new apparatus combines the long-range interactions found in dipolar quantum gases with the single-site resolution found in quantum gas microscopes. Ultracold dipolar quantum gases are a powerful and versatile platform to study quantum phenomena in and out of equilibrium. The large magnetic moment of dysprosium atoms allows for long-range and anisotropic interactions that give rise to exotic states of matter. By implementing a quantum gas microscope, microscopic details such as site occupation and site correlations will be observable. We plan to do this using magnetic atoms trapped in an ultraviolet optical lattice with a lattice spacing of a ≈ 180 nm. Combined with the long-range dipole interaction (∝ 1/r3), the short lattice spacing will significantly increase the nearest-neighbour interaction strength to be on the order of 200 Hz (10 nK). This will allow us to study the regime of strongly interacting dipolar Bose-/and Fermi-Hubbard physics where even next-nearest-neighbour interactions could be visible. Our upcoming dipolar quantum gas microscope will enable further studies relating to quantum simulations and quantum magnetism.
