A Large Atom Number Metastable Helium Bose-Einstein Condensate
A. S. Tychkov, T. Jeltes, J. M. McNamara +4
We have produced a Bose-Einstein condensate of metastable helium (4He*) containing over 1.5x10^7 atoms, which is a factor of 25 higher than previously achieved. The improved starti…

Theory of evaporative cooling with energy-dependent elastic scattering cross section and application to metastable helium
Paul J. J. Tol, W. Hogervorst, W. Vassen
The kinetic theory of evaporative cooling developed by Luiten et al. [Phys. Rev. A 53, 381 (1996)] is extended to include the dependence of the elastic scattering cross section on…

Effect of atomic transfer on the decay of a Bose-Einstein condensate
Pawel Zin, Andrzej Dragan, Szymon Charzynski +4
We present a model describing the decay of a Bose-Einstein condensate, which assumes the system to remain in thermal equilibrium during the decay. We show that under this assumptio…
