Observation of Bose-Einstein Condensation of Molecules
M. W. Zwierlein, C. A. Stan, C. H. Schunck +4
We have observed Bose-Einstein condensation of molecules. When a spin mixture of fermionic Li-6 atoms was evaporatively cooled in an optical dipole trap near a Feshbach resonance,…
Dissociation and Decay of Ultra-cold Sodium Molecules
T. Mukaiyama, J. R. Abo-Shaeer, K. Xu +2
The dissociation of ultracold molecules is studied by ramping an external magnetic field through a Feshbach resonance. The observed dissociation energy shows non-linear dependence…
Distillation of Bose-Einstein condensates in a double-well potential
Y. Shin, M. Saba, A. Schirotzek +4
Bose-Einstein condensates of sodium atoms, prepared in an optical dipole trap, were distilled into a second empty dipole trap adjacent to the first one. The distillation was driven…
Buffer gas cooling and trapping of atoms with small magnetic moments
J. G. E. Harris, R. A. Michniak, S. V. Nguyen +2
Buffer gas cooling was extended to trap atoms with small magnetic moment (mu). For mu greater than or equal to 3mu_B, 1e12 atoms were buffer gas cooled, trapped, and thermally isol…
Raman Amplification of Matter Waves
Dominik Schneble, Gretchen K. Campbell, Erik W. Streed +3
We demonstrate a Raman amplifier for matter-waves, where the amplified atoms and the gain medium are in two different hyperfine states. This amplifier is based on a novel form of s…
Formation of Quantum-Degenerate Sodium Molecules
K. Xu, T. Mukaiyama, J. R. Abo-Shaeer +3
Ultra-cold sodium molecules were produced from an atomic Bose-Einstein condensate by ramping an applied magnetic field across a Feshbach resonance. More than molecules were…
