Description
We present our current progress towards a quantum gas microscope apparatus for experiments with ultracold dysprosium atoms exhibiting long-range dipole-dipole interactions (DDI). In addition to its large permanent magnetic dipole moment, Dy offers a set of closely-spaced opposite parity states (OPS), that can be dressed by microwave radiation to give rise to a tunable electric DDI. This approach can be used to simulate complex spin models (such as the XYZ model) and avoids some of the technical challenges of other platforms (e.g. heteronuclear molecules). The primary tool of our apparatus is a high-resolution microscope [1]. We show our current progress towards loading and positioning the atomic sample in a single 2D plane coincident with the the focal plane of the microscope with the help of a beat-note lattice [2]. For achieving single-site imaging resolution we recently added an incoherent light source, which will be used to engineer a 2D matter-wave magnifier [3]. Recently, this source has also been used together with a digital micromirror device (DMD) to shape arbitrary trapping potentials. Furthermore, we show preliminary spectroscopic data towards the efficient population of the OPS via stimulated Raman adiabatic passage (STIRAP).
