Closeup of the dark energy source sphereThe basic premise of our work is that precision measurements of fundamental quantities can help physicists address fundamental questions - for example, to find and verify physics beyond the standard model. While the energy scale of such physics is typically beyond the reach of experiments, it is possible to probe for suppressed effects at attainable energies in experiments of outstanding precision. Our work applies methods from atomic, molecular, and optical physics. It is centered on advancing the experimental technology to push the sensitivity of experiments to new levels, and to perform precision measurements of fundamental quantities. Examples are atom interferometry and testing Lorentz invariance.

Our current main projects are

Cavity interferometry to sense suppressed "fifth forces,"

Precision measurement of the fine structure constant using Bragg-Bloch atom interferometry,

Interferometry with cold lithium atoms,

Compact inertial sensing, and

Testing Lorentz symmetry with rotating crystal oscillators.
