Journal ArticleDOI
Bose-Einstein condensation of molecules
Selim Jochim,M. Bartenstein,M. Bartenstein,A. Altmeyer,A. Altmeyer,G. Hendl,G. Hendl,S. Riedl,S. Riedl,Cheng Chin,Cheng Chin,J. Hecker Denschlag,J. Hecker Denschlag,Rudolf Grimm,Rudolf Grimm +14 more
TL;DR: It is reported on the Bose-Einstein condensation of more than 105 Li2 molecules in an optical trap starting from a spin mixture of fermionic lithium atoms and demonstrated the magnetic field–dependent mean field by controlled condensate spilling.
Journal ArticleDOI
Crossover from a molecular Bose-Einstein condensate to a degenerate Fermi gas.
M. Bartenstein,A. Altmeyer,S. Riedl,Selim Jochim,Cheng Chin,J. Hecker Denschlag,Rudolf Grimm,Rudolf Grimm +7 more
TL;DR: A reversible conversion of a 6Li2 molecular Bose-Einstein condensate to a degenerate Fermi gas of atoms by adiabatically crossing a Feshbach resonance is demonstrated.
Journal ArticleDOI
Observation of the Pairing Gap in a Strongly Interacting Fermi Gas
Cheng Chin,M. Bartenstein,A. Altmeyer,S. Riedl,Selim Jochim,J. Hecker Denschlag,Rudolf Grimm,Rudolf Grimm +7 more
TL;DR: In this article, the authors studied fermionic pairing in an ultracold two-component gas of 6Li atoms by observing an energy gap in the radio-frequency excitation spectra.
Journal ArticleDOI
Collective Excitations of a Degenerate Gas at the BEC-BCS Crossover
M. Bartenstein,A. Altmeyer,S. Riedl,Selim Jochim,Cheng Chin,J. Hecker Denschlag,Rudolf Grimm,Rudolf Grimm +7 more
TL;DR: In the regime of a strongly interacting Fermi gas, an abrupt change in the collective excitation frequency occurs, which may be a signature for a transition from a superfluid to a collisionless phase.
Journal ArticleDOI
Pure gas of optically trapped molecules created from fermionic atoms.
Selim Jochim,M. Bartenstein,A. Altmeyer,G. Hendl,Cheng Chin,J. Hecker Denschlag,Rudolf Grimm +6 more
TL;DR: The production of a pure sample of up to 3 x 10(5) optically trapped molecules from a Fermi gas of 6Li atoms using a Stern-Gerlach selection technique that efficiently removes all trapped atoms from the atom-molecule mixture.
