Feshbach Resonances in Fermionic Lithium-6
C. H. Schunck, M. W. Zwierlein, C. A. Stan +6
Feshbach resonances in lithium-6 were experimentally studied and theoretically analyzed. In addition to two previously known s-wave resonances, we found three p-wave resonances. Fo…
Observation of Feshbach resonances between two different atomic species
C. A. Stan, M. W. Zwierlein, C. H. Schunck +2
We have observed three Feshbach resonances in collisions between lithium-6 and sodium-23 atoms. The resonances were identified as narrow loss features when the magnetic field was v…
Fifty-fold improvement in the number of quantum degenerate fermionic atoms
Z. Hadzibabic, S. Gupta, C. A. Stan +4
We have produced a quantum degenerate Li-6 Fermi gas with up to 7 x 10^7 atoms, an improvement by a factor of fifty over all previous experiments with degenerate Fermi gases. This…
Coherent Collisions between Bose-Einstein Condensates
J. M. Vogels, J. K. Chin, W. Ketterle
We study the non-degenerate parametric amplifier for matter waves, implemented by colliding two Bose-Einstein condensates. The coherence of the amplified waves is shown by observin…
Sodium Bose-Einstein Condensates in the F=2 State in a Large-volume Optical Trap
A. Görlitz, T. L. Gustavson, A. E. Leanhardt +6
We have investigated the properties of Bose-Einstein condensates of sodium atoms in the upper hyperfine ground state in a purely optical trap. Condensates in the high-field seeking…
Generation of macroscopic pair-correlated atomic beams by four-wave mixing in Bose-Einstein condensates
J. M. Vogels, K. Xu, W. Ketterle
By colliding two Bose-Einstein condensates we have observed strong bosonic stimulation of the elastic scattering process. When a weak input beam was applied as a seed, it was ampli…
