Session 1

The exchange of new light(ish) bosons coupled to electrons and nucleons leads to extra forces and corresponding potentials between particles and even macroscopic bodies. The high accuracy achievable in measurements on atoms and ions provides a powerful laboratory to test these forces at atomic and smaller distances. We discuss new tests of axion-like particles in highly charged ions, but also...

Session 1

I consider the quantum sensing of gravity and rotation fields
using spatially localized probes (trapped systems) of ultracold quantum gases of interacting atoms or molecules.
It is shown that to achieve an accurate statement on the optimality
of a given measurement protocol, it is mandatory to go beyond the standard quantum optics paradigm of describing the system by a Hamiltonian...
