We present a method for determining the phase and contrast of a single shot of an atom
interferometer. The application of a phase shear across the atom ensemble yields a spatially …

This thesis presents experimental results from the Stanford 10 m atom drop tower. We use
atomic physics and laser spectroscopic techniques to test both general relativity and …

We investigate the characteristics of near resonant Bragg scattering, the underlying process
that produces a signal in a grating-echo atom interferometer. We explore how the density …

In this paper, a compact laser system for 87Rb atom interferometry based on only one free-
space electro-optic modulator (EOM) was realized, where repumping and Raman beams …

We investigate channeling oscillations in the contrast of a density grating formed by
exposing a sample of ultracold atoms to an optical standing-wave pulse. We show that these …

Echo atom interferometers have emerged as interesting alternatives to Raman
interferometers for the realization of precise measurements of the gravitational acceleration …

We discuss techniques for probing the effects of a constant force acting on cold atoms using
two configurations of a grating echo-type atom interferometer. Laser-cooled samples of 85 …

We have developed a new technique for measuring the atomic recoil frequency using a
singlestate echo type atom interferometer that manipulates laser cooled atoms in the ground …

We describe progress toward a precise measurement of the recoil energy of an atom
measured using a modified grating-echo atom interferometer (AI) that involves three …

We study the resonance interaction between two entangled identical atoms coupled to a
quantized scalar field vacuum and accelerating between two mirrors. We show how …
