Influence of the Coriolis force in atom interferometry

Phys Rev Lett. 2012 Mar 2;108(9):090402. doi: 10.1103/PhysRevLett.108.090402. Epub 2012 Feb 27.


In a light-pulse atom interferometer, we use a tip-tilt mirror to remove the influence of the Coriolis force from Earth's rotation and to characterize configuration space wave packets. For interferometers with a large momentum transfer and large pulse separation time, we improve the contrast by up to 350% and suppress systematic effects. We also reach what is to our knowledge the largest space-time area enclosed in any atom interferometer to date. We discuss implications for future high-performance instruments.
