Very high precision bound state spectroscopy near a Rb Feshbach resonance
N. R. Claussen, S. J. J. M. F. Kokkelmans, S. T. Thompson +2
We precisely measured the binding energy of a molecular state near the Feshbach resonance in a Rb Bose-Einstein condensate (BEC). Rapid magnetic field pulses induced coheren…
Atom--Molecule Coherence in a Bose-Einstein Condensate
Elizabeth A. Donley, Neil R. Claussen, Sarah T. Thompson +1
Coherent coupling between atoms and molecules in a Bose-Einstein condensate (BEC) has been observed. Oscillations between atomic and molecular states were excited by sudden changes…
Microscopic Dynamics in a Strongly Interacting Bose-Einstein Condensate
N. R. Claussen, E. A. Donley, S. T. Thompson +1
An initially stable 85Rb Bose-Einstein condensate (BEC) was subjected to a carefully controlled magnetic field pulse in the vicinity of a Feshbach resonance. This pulse probed the…
Dynamics of collapsing and exploding Bose-Einstein condensates
Elizabeth A. Donley, Neil R. Claussen, Simon L. Cornish +3
We explored the dynamics of how a Bose-Einstein condensate collapses and subsequently explodes when the balance of forces governing the size and shape of the condensate is suddenly…
Improved Characterization of Elastic Scattering Near a Feshbach Resonance in 85Rb
J. L. Roberts, J. P. Burke, N. R. Claussen +3
We report extentions and corrections to the measurement of the Feshbach resonance in 85Rb cold atom collisions reported earlier [J. L. Roberts et al., Phys. Rev. Lett. 81, 5109 (19…
Controlled Collapse of a Bose-Einstein Condensate
J. L. Roberts, N. R. Claussen, S. L. Cornish +3
The point of instability of a Bose-Einstein Condensate (BEC) due to attractive interactions was studied. Stable 85-Rb BECs were created and then caused to collapse by slowly changi…
Stable 85Rb Bose-Einstein Condensates with Widely Tunable Interactions
S. L. Cornish, N. R. Claussen, J. L. Roberts +2
Bose-Einstein condensation has been achieved in a magnetically trapped sample of 85Rb atoms. Long-lived condensates of up to 10^4 atoms have been produced by using a magnetic-field…
Magnetic Field Dependence of Ultracold Inelastic Collisions near a Feshbach Resonance
J. L. Roberts, N. R. Claussen, S. L. Cornish +1
Inelastic collision rates for ultracold Rb atoms in the F=2 m=-2 state have been measured as a function of magnetic field. Dramatic change in the vicinity of a Feshbac…
Resonant magnetic field control of elastic scattering of cold 85Rb
J. L. Roberts, N. R. Claussen, James P. Burke +3
A magnetic field dependent Feshbach resonance has been observed in the elastic scattering collision rate between atoms in the F = 2, M = -2 state of 85 Rb. Changing the magnetic fi…
