Tests of Fundamental Physics: Gravity

Tests of Fundamental Physics: Gravity

Design and realisation of tests of General Relativity, studying gravity at very short distances, relativistic effects in matter wave interferometers.

Activities

  • Sophisticated tests of Einsteins's theory of relativity, e.g. possible temporal variation of the gravitational constant, test of the weak and strong equivalence principle, Yukawa-test for the Earth-Moon distance, estimation of metric parameters gamma and alpha
  • Measuring gravity at short distances with micro-machined optomechanical force sensors and levitated nanoparticle based force sensors
  • Relativistic effects in matter wave interferometers, quantum tests of the equivalence principle, dark energy search in the Einstein Elevator
  • Clock tests in gravitational fields
  • Testing local Lorentz invariance with classical and quantum systems in the solar system
  • Tests of fundamental properties of quantum mechanics, including tests of the interaction of quantum systems with gravitation
