Building the most precise atomic clocks in the world by studying many-body physics
About 60 years ago, the second was defined by the Earth’s rotation. However, with the discovery of quantum mechanics it became clear that atomic clocks could be significantly more accurate and more precise. Thus, in 1967 the second was redefined in terms of an atomic transition in cesium atoms. While currently single trapped ion clocks are at the forefront, neutral atom optical clocks have the potential to outperform the latter due to the possibility to simultaneously interrogate a large number of neutral atoms; This will be however only possible if we can understand and control atom-atom interactions. In this talk I am going to describe our progress in this direction and explain why a precise characterization of the many-body physics could be extremely useful for quantum information sciences.
