Atomic dynamics in evaporative cooling of trapped alkali atoms in strong magnetic fields
O. H. Pakarinen, K. -A. Suominen
We investigate how the nonlinearity of the Zeeman shift for strong magnetic fields affects the dynamics of rf field induced evaporative cooling in magnetic traps. We demonstrate fo…
The validity of the Landau-Zener model for output coupling of Bose condensates
J. -P. Martikainen, K. -A. Suominen
We investigate the validity of the Landau-Zener model in describing the output coupling of Bose condensates from magnetic traps by a chirped radiofrequency field. The predictions o…
Collisions of cold magnesium atoms in a weak laser field
Mette Machholm, Paul S. Julienne, Kalle-Antti Suominen
We use quantum scattering methods to calculate the light-induced collisional loss of laser-cooled and trapped magnesium atoms for detunings up to 30 atomic linewidths to the red of…
