An apparatus to create ultracold gases of bosonic and fermionic ground state NaK molecules

Quantum gases of molecules with long-range, anisotropic dipolar interactions offer an exceptional platform to explore exotic quantum many-body physics, precision measurements, and quantum information processing. Here, we present an apparatus designed to produce ultracold gases of bosonic ²³Na⁴¹K and fermionic ²³Na⁴⁰K molecules within a single experimental system. To this end, we demonstrate that ²³Na, which is known to be an efficient sympathetic coolant for fermionic ⁴⁰K, is also an effective coolant for bosonic ⁴¹K. A degenerate Bose-Bose mixture of ²³Na-⁴¹K is created, and their Feshbach resonances are investigated, which serves as the starting point for the formation of their ground state molecules. Further experimental progress and outlook will be briefly discussed.
