Fundamental physics applications of atom interferometry

Kurzfassung

Quantum sensors based on atom interferometry have demonstrated a great potential as high-precision inertial sensors, in metrological applications and in fundamental physics measurements. In this talk I will explain how they can be exploited for accurate measurements of the fine-structure constant and the gravitational constant G, tests of the equivalence principle in the quantum regime, and direct searches of dark energy and ultralight dark-matter fields. Key aspects for attaining the required sensitivities will be discussed.
