Abstract: While there is tremendous astrophysical and cosmological evidence for dark matter, its precise nature is one of the biggest open questions in modern physics. The DarkSide experiment is looking for WIMP dark matter using a liquid argon target located deep underground at Gran Sasso National Laboratory (LNGS) in Italy. DarkSide-50 is the…

The ability to control the quantum degrees of freedom of atoms using laser light opened the way to precision measurements of fundamental physical quantities. After an introduction to the methods allowing us to cool a cloud of atoms to temperatures close to the absolute zero, I will de-scribe experiments for precision tests of gravitational…
