We have recently produced a BEC of 85Rb. A broad, low field Feshbach resonance allows us to tune the interactions of atoms in the condensate from attractive to zero to repulsive. We intend to pursue experiments with interaction free atom lasers and analog systems such as the 'Bosenova'. Actually, our list of ideas for experiments is longer than our arms (both!)...
The image to the left shows a 85Rb condensate forming from a thermal cloud, as the temperature of the atom cloud is lowered.
