Trapped atom interferometry for precision gravity surveys and fundamental physics

Gravity holds great potential as a sensing channel: all matter gravitates, and this effect cannot be shielded. Gravity is so weak however, that extraordinary sensitivity is required to actualize this potential. In this talk, I will discuss a novel atomic gravimeter configuration that (a) has sufficient sensitivity to be a useful gravitational sensor, (b) is small, light and robust enough to operate as a mobile payload, and (c) has excellent spatial resolution for laboratory-scale fundamental physics research.
