Potassium condensates in optical tweezers

We present progress on the design and construction of a compact, potassium based neutral cold atom machine which will combine the high precision spatial control of optical tweezers with the creation of degenerate quantum gasses. The machine leverages the small fine and hyperfine structures, and broad Feshbach resonances of potassium, to minimize vector light shifts in tweezers and provide the necessary control over atom-atom interactions for evaporative cooling to quantum degeneracy. With these capabilities we aim to explore fundamental new directions in quantum thermodynamics, simulation of many-body phenomena, and entanglement generation.
