Description

Gravity Resonance Spectroscopy (GRS) investigates the energy states of Ultra-Cold Neutrons using an equivalent of Ramsey's method of separated oscillating fields. The manipulation of states is realized using mechanical oscillations instead of EM fields. This allows direct investigation of some "beyond-Riemann" gravity models as well as specific DM and DE candidates. An overview of current status and results from the ILL is given. Experimental challenges for a successful measurement campaign are discussed.
