The Bose-Einstein condensate

January 1, 1998
Author(s)
Eric A. Cornell, C E. Wieman
In June 1995, our research group at the Joint Institute for Laboratory Astrophysics in Bolder, Colorado, succeeded in creating a miniscule but marvelous droplet. By cooling 2,000 rubidium atoms to a temperature less than 100 billionths of a degree above

The creation and study of Bose-Einstein condensation in a cold alkali vapor

September 1, 1997
Author(s)
C E. Wieman, Eric A. Cornell, Deborah S. Jin, J R. Ensher
Bose-Einstein condensation in a gas resulted form the combination of research in laser cooling and trapping, the study of spin polarized hydrogen, and the investigation of atomic collisions at very low temperatures. After discussing how these advances led

Optical-Dipole-Force-Fiber Guiding and Heating of Atoms

May 1, 1997
Author(s)
M J. Renn, A A. Zozulya, E A. Donley, Eric A. Cornell, D Z. Anderson
We use optical dipole forces to guide atoms through hollow-core optical fibers. Laser light is focused into the hollow region of 40 υm inner diameter capillary fiber and guided through the fiber by grazing incidence reflection from the glass walls. The

Production of Two Overlapping Bose-Einstein Condensates by Sympathetic Cooling

January 1, 1997
Author(s)
C J. Myatt, E A. Burt, R W. Ghrist, Eric A. Cornell, C E. Wieman
A double magneto-optic trap apparatus with a number of desirable features was used to create condensates of 2x10 6 atoms in either of the F=2, m=2 or F=1, m=-1 spin states of 87Rb. Overlapping condenstates of the two states were also created using nearly
