Longitudinal Atom Optics : Measuring the Density Matrix of a Matter Wave Beam by Richard Alan Rubenstein

This thesis describes recent developments of theoretical and experimental techniques for longitudinal atom optics and interferometry, in which time-dependent interactions are used to create coherences in the longitudinal momentum of a matter wave. We present a fully quantum mechanical treatment of the classic molecular beams resonance experiment, a beam of two state particles interacting with t...

Ultra-high Sensitivity Accelerometers and Gyroscopes Using Neutral Atom Matter-wave Interferometry*

This paper shows that matter-wave interferometers employing low-velocity neutral atoms can be used as inertial sensors with sensitivities that exceed those of conventional mechanical sensors and multiple circuit optical interferometers by many powers of ten. The energy and mass dependence of the phase shifts that are due to rotation and acceleration are different. Thus a pair of interferometers...

Combined chips for atom optics

We present experiments with Bose-Einstein condensates on a combined atom chip. The combined structure consists of a large-scale “carrier chip” and smaller “atom-optics chips,” containing micron-sized elements. This allows us to work with condensates very close to chip surfaces without suffering from fragmentation or losses due to thermally driven spin flips. Precise three-dimensional positionin...
