Electron Temperature of Ultracold Plasmas
J. L. Roberts, C. F. Fertig, M. L. Lim +1
We study the evolution of ultracold plasmas by measuring the electron temperature. Shortly after plasma formation, competition between heating and cooling mechanisms drives the ele…
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…
