Atom Wave Interferometers

Long-term research objective Matter wave interferometers, in which de Broglie waves are coherently split and then recombined to produce interference fringes, have opened exciting new possibilities for precision and fundamental measurements with complex particles. The aim of our research program is to extend the ideas and techniques of atom optics and atom interferometry which underlie atom inteeferometers, to use these devices to make qualitatively new andor more precise measurements in atomic physics, and to perform fundamental experiments in quantum mechanics based on our ability to measure interactions that displace the de Broglie wave phase or change the quantum coherence of the beams reducing the amplitude of the interference pattern.
