Bloch oscillations in atom interferometry

Atomic Physics 2016-04-20 v1 Quantum Physics

Abstract

In Paris, we are using an atom interferometer to precisely measure the recoil velocity of an atom that absorbs a photon. In order to reach a high sensitivity, many recoils are transferred to atoms using the Bloch oscillations technique. In this lecture, I will present in details this technique and its application to high precision measurement. I will especially describe in details how this method allows us to perform an atom recoil measurement at the level of 1.3×1091.3 \times 10^{-9}. This measurement is used in the most precise determination of the fine structure constant that is independent of quantum electrodynamics.
