We present the progress of our dipolar quantum gas microscope, which will enable single particle and single site resolved detection of Dysprosium atoms.
Our optical setup allows for the integration of both square and triangular lattice geometries (utilizing a wavelength of 360 nm), offering the capability to observe and manipulate diverse quantum phase transitions such as the (fractional) mott insulator to supersolid transitions. We present our design of an accordion lattice, a versatile optical trapping system, for loading Dysprosium atoms into the optical lattice. Additionally, our method to efficiently transport ultra-cold atoms from another vacuum chamber into the accordion lattice will be presented.
We will utilise an objective with a high numerical aperture (NA=0.9) and employ a spin- and energy-resolved super-resolution imaging technique, allowing us to achieve single-site detection with 180 nm resolution. The close spacing of the ultraviolet optical lattice significantly amplifies the nearest-neighbor dipolar interactions, reaching approximately 200 Hz (at 10 nK). This places us in the regime of strongly interacting Bose- and Fermi-Hubbard physics.
