A simple model of Feshbach molecules
Cheng Chin
We present a two-channel model to describe the quantum state of two atoms with finite-range interaction near a Feshbach resonance. This model provides a simple picture to analytica…
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…
Optimized production of a cesium Bose-Einstein condensate
Tobias Kraemer, Jens Herbig, Michael Mark +4
We report on the optimized production of a Bose-Einstein condensate of cesium atoms using an optical trapping approach. Based on an improved trap loading and evaporation scheme we…
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…
