Atoms few, damned but quick… In our Lab, magnetic fields sources, RF antennas, optical structures, are all integrated in a micro-chip with a Bose-Einstein condensate a few hundred microns from the surface: an "Atom chip". One of the primary tools for handling ultra-cold atoms is the magnetic trap, which is needed both during cooling and during the experiment. In addition to macroscopic coils, it can be also possible to produce the necessary magnetic fields using the current circulating in a suitable gold and silicon chip a few inches from the surface. Our activity is dedicated to the application of AtomChips to Quantum Technologies.
