Observation of spinor dynamics in optically trapped 87Rb Bose-Einstein Condensates (2003)
Hamley, C. D., Barrett, M. D., Sauer, J. A., Fortier, K. M., Zhang, W., ...
We measure spin mixing of F=1 and F=2 spinor condensates of 87Rb atoms confined in an optical trap. We determine the spin mixing time to be typically less than 600 ms and observe spin population...
Cavity QED with optically transported atoms (2003)
Sauer, J. A., Fortier, K. M., Chang, M. S., Hamley, C. D., Chapman, M. S.
Ultracold $^{87}$Rb atoms are delivered into a high-finesse optical micro-cavity using a translating optical lattice trap and detected via the cavity field. The atoms are loaded into an optical...
A Storage Ring for Neutral Atoms (2001)
Sauer, J. A., Barrett, M. D., Chapman, M. S.
We have demonstrated a storage ring for ultra-cold neutral atoms. Atoms with mean velocities of 1 m/s corresponding to kinetic energies of ~100 neV are confined to a 2 cm diameter ring by magnetic...
All Optical Formation of an Atomic Bose-Einstein Condensate (2001)
Barrett, M. D., Sauer, J. A., Chapman, M. S.
We have created a Bose-Einstein condensate of 87Rb atoms directly in an optical trap. We employ a quasi-electrostatic dipole force trap formed by two crossed CO_2 laser beams. Loading directly from a...
Effect of High Pressure on Properties of Polymers. (1998)
The results of the research studies carried out during the last three and a half years concerning the effects of hydrostatic pressure on the mechanical behavior and mechanical properties of the...
Effects Of Hydrostatic Pressure On The Mechanical Behavior Of Polyethylene And Polypropylene (1998)
Mears, D.R., Pae, K.D., Sauer, J.A.
An apparatus has been designed and constructed that will allow determination of the mechanical behavior of polymer specimens subject to applied tensile and compressive loading, while the sample is...
Sauer, J.A., Mears, D.R., Pae, K.D.
The effects of hydrostatic pressure (up to 100,000 psi) on the stress-strain behavior of a highly crystalline polymer (polytetrafluoroethylene) and an amorphous polymer (polycarbonate) have been...
