Resonances in ultracold collisions involving heavy molecules are difficult to simulate
theoretically and have proven challenging to detect. Here we report the observation of …

Understanding collisions between ultracold molecules is crucial for making stable molecular
quantum gases and harnessing their rich internal degrees of freedom for quantum …

We report the creation of ultracold bosonic dipolar Na 23 K 39 molecules in their absolute
rovibrational ground state. Starting from weakly bound molecules immersed in an ultracold …

Coherence, the stability of the relative phase between quantum states, is central to quantum
mechanics and its applications. For ultracold dipolar molecules at sub-microkelvin …

In this work we model and realize stimulated Raman adiabatic passage (STIRAP) in the
diatomic 23 Na 40 K molecule from weakly bound Feshbach molecules to the rovibronic …

Time crystals, a phase showing spontaneous breaking of time-translation symmetry, has
been an intriguing subject for systems far away from equilibrium. Recent experiments found …

We present measurements of more than 80 magnetic Feshbach resonances in collisions of
ultracold 23 Na 40 K with 40 K. We assign quantum numbers to a group of low-field …

We demonstrate coherent microwave control of rotational and hyperfine states of trapped,
ultracold, and chemically stable Na 23 K 40 molecules. Starting with all molecules in the …

We have demonstrated the resonant control of the elastic scattering cross sections in the
vicinity of Feshbach resonances between Na 23 K 40 molecules and K 40 atoms by studying …

We demonstrate the transfer of Na 23 K 40 molecules from a closed-channel-dominated
Feshbach-molecule state to the absolute ground state. The Feshbach molecules are initially …
