Abstract

Strong magnetic interactions in ultracold quantum gases lead to self-organization of macroscopic patterns such as supersolid quantum droplets when the atoms confined in bulk. Microscopically the very same interactions facilitate quantum simulations of extended Hubbard models when these atoms are confined to a lattice. We theoretically investigate the phase diagram of strongly dipolar quantum gases confined in bulk and show that beyond the droplet regime honeycomb and labyrinthine states form, which are candidates for a new type of supersolid and superglass respectively. We also report on our progress building an experimental apparatus designed to capture dipolar atoms in bulk and transport them to a quantum gas microscope chamber where they populate an ultraviolet optical lattice. The narrow spacing of this lattice enables strong next-nearest neighbor interactions and requires the use of state-of-the art photonics, super-resolution techniques and precise magnetic field control for efficient readout of site populations.
