Interferometry with Interacting Bose-Einstein Condensates in a Double-Well Potential

This thesis demonstrates a full Mach–Zehnder interferometer with interacting Bose–Einstein condensates confined on an atom chip. This requires the development of atom-optics analogues to beam splitters, phase shifters and recombiners.

Particle interactions in the Bose–Einstein condensate lead to a nonlinearity, absent in photon optics.
