Visualization of Bose-Einstein Condensates

March 1, 1999
Author(s)
Peter M. Ketcham, D L. Feder, W P. Reinhardt, Charles W. Clark, William L. George
A Bose-Einstein condensate (BEC) is a state of matter that exists at extremely low temperatures.BECs are currently under investigation through both numerical simulation and laboratory experiments.The visualization of data generated by numerical simulation

Trapped Bose-Einstein Condensates at Finite Temperature: A Two-Gas Model

January 1, 1998
Author(s)
Karen G. Burnett, M Edwards, Charles W. Clark, R J. Dodd
A simple picture describes the results of recent treatments of partially-condensed, dilute, trapped Bose gases at temperature T>O. The condensate wavefunction is nearly identical to that of a T=O condensate with the same number of condensate atoms, No. The

Local-density-functional calculations of the Energy of Atoms

January 1, 1997
Author(s)
Svetlana A. Kotochigova, Zachary H. Levine, Eric L. Shirley, Mark D. Stiles, Charles W. Clark
The total energies of atoms and with atomic number Ζ from 1 to 92 and singly-charge cations with Ζ from 2 to 92 have been calculated to an accuracy of 1 υHartree within four variants of the Kohn-Sham local-density approximation. The approximations
