Precision Inertial Measurements with Cold Atom Interferometers

De Rémi Geiger

After more than 25 years of fundamental research, atom interferometers have reached sensitivity and accuracy levels competing with or beating inertial sensors based on different technologies. Cold-atom interferometers offer interesting applications in geosciences (measurements of the acceleration of free fall or of the Earth rotation rate), inertial sensing (autonomous positioning of a mobile), metrology (redefinition of the kilogram) and fundamental physics (tests of the laws of gravitation, gravitational wave astronomy). In this seminar, I will present the principle of an atom interferometer and describe experiments performed at the SYRTE laboratory in the last years to illustrate the possible applications of cold-atom inertial sensors.
