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…
A simple mean field equation for condensates in the BEC-BCS crossover regime
Cheng Chin
We present a mean field approach based on pairs of fermionic atoms to describe condensates in the BEC-BCS crossover regime. By introducing an effective potential, the mean field eq…
Radio-Frequency Transitions on Weakly-Bound Ultracold Molecules
Cheng Chin, Paul S. Julienne
We show that radio-frequency spectroscopy on weakly-bound molecules is a powerful and sensitive tool to probe molecular energy structure as well as atomic scattering properties. An…
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…
