Efficient creation of molecules from a cesium Bose-Einstein condensate
M. Mark, T. Kraemer, J. Herbig +3
We report a new scheme to create weakly bound Cs molecules from an atomic Bose-Einstein condensate. The method is based on switching the magnetic field to a narrow Feshbach res…
Observation of the Pairing Gap in a Strongly Interacting Fermi Gas
C. Chin, M. Bartenstein A. Altmeyer, S. Riedl +3
We study fermionic pairing in an ultracold two-component gas of Li atoms by observing an energy gap in the radio-frequency excitation spectra. With control of the two-body inte…
Collective excitations of a degenerate gas at the BEC-BCS crossover
M. Bartenstein, A. Altmeyer, S. Riedl +4
We study collective excitation modes of a fermionic gas of Li atoms in the BEC-BCS crossover regime. While measurements of the axial compression mode in the cigar-shaped trap c…
Crossover from a molecular Bose-Einstein condensate to a degenerate Fermi gas
M. Bartenstein, A. Altmeyer, S. Riedl +4
We demonstrate a reversible conversion of a Li2 molecular Bose-Einstein condensate to a degenerate Fermi gas of atoms by adiabatically crossing a Feshbach resonance. By optical in…
Thermal equilibrium and efficient evaporation of an ultracold atom-molecule mixture
Cheng Chin, Rudolf Grimm
We derive the equilibrium conditions for a thermal atom-molecule mixture near a Feshbach resonance. Under the assumption of low collisional loss, thermodynamical properties are cal…
Pure Gas of Optically Trapped Molecules Created from Fermionic Atoms
S. Jochim, M. Bartenstein, A. Altmeyer +4
We report on the production of a pure sample of up to 3x10^5 optically trapped molecules from a Fermi gas of 6Li atoms. The dimers are formed by three-body recombination near a Fes…
