Toward quantum domain new generation of experiments with laser cooled he

Objective



The pursuit of this program is to continue the recent work on a advanced and unique setup of VSCP trapped He* atoms*) and to extend the experiment to the study of first and higher order atomic interference. Here, pushing the actual experiment towards the highest possible density of trapped atoms is the central purpose of this proposal. Within this frame the application of new technologies for trapping (dark state traps or spin-vortex traps) as well as the investigation of loss mechanisms (Penning collisions) will cover more than one year. In the second half of the program the new set-up is expected to achieve densities large enough to provide a brilliant source for a cold-atom interferometer to study atomic coherence**) or to enable Hanbury-Brown Twiss experiments***) to search for quantum statistical effects.
