Ultracold Atom Gyroscope

The goal of this project is to demonstrate an ultracold atom gyroscope sensitive enough to detect the Earth’s rotation. To do this we trap 87Rb atoms in a cigar-shaped, high frequency magnetic trap created from an atom chip depicted below. We then cool the atoms to degeneracy and use a Sagnac interferometer geometry to perform the inertial sensing.

Putting Cold Atoms in Space

The Cold Atom Laboratory (CAL) is being designed to enable earth-bound researchers to carry out ultracold atom physics experiments in the micro-gravity environment of the International Space Station (ISS). Earth-bound experiments are subject to acceleration due to the Earth's gravity, and the corresponding energy shifts can be large compared with the temperature and quantum mechanical energy of ultracold atoms. Setting gravity to nearly zero allows one to carry out experiments and observations not possible with table-top experiments on Earth.
