We prepare mixtures of ultracold ^{39}K atoms in various hyperfine spin states with ^{23}Na^{39}K molecules in an optical dipole trap at a fixed magnetic field and study inelastic two-body atom-molecule collisions. We observe atom-molecule losses tha

We investigate the strong out-of-equilibrium dynamics occurring when a harmonically trapped ultracold bosonic gas is evaporatively cooled across the Bose--Einstein condensation transition. By imaging the cloud after free expansion, we study how the c

We probe photoinduced loss for chemically stable bosonic $^{23}\mathrm{Na}^{87}\mathrm{Rb}$ and $^{23}\mathrm{Na}^{39}\mathrm{K}$ molecules in chopped optical dipole traps, where the molecules spend a significant time in the dark. We expect the effec

We report the creation of ultracold bosonic dipolar $^{23}\mathrm{Na}^{39}\mathrm{K}$ molecules in their absolute rovibrational ground state. Starting from weakly bound molecules immersed in an ultracold atomic mixture, we coherently transfer the dim

Formation of ultracold weakly bound dimers of bosonic 23Na39K

Publikováno v: Physical Review A. 101

We create weakly bound bosonic ${}^{23}{\mathrm{Na}}^{39}\mathrm{K}$ molecules in a mixture of ultracold $^{23}\mathrm{Na}$ and $^{39}\mathrm{K}$. The creation is done in the vicinity of a so far undetected Feshbach resonance at about 196 G which we
