qBounce: Ramsey Spectroscopy to test Newtons Inverse Square Law at micron distances using UCN
In the last years, gravity experiments have been experiencing a renaissance for several reasons: Modern astronomical observations clearly point to the existence of dark energy and dark matter. Their true nature and content remain a mystery however. Furthermore, prominent candidates to formulate a consistent quantum theory of gravitation require extra spatial dimensions. The neutron is an ideal tool to answer such questions. More precisely, gravitational quantum states of ultra-cold neutrons connect gravity experiments at short distances with powerful resonance spectroscopy techniques. As in many other examples in science, this connection has the potential to an at least order-of-magnitude improvement in sensitivity. Here, we propose to push the limits of the qBOUNCE experiments one step further and to apply Ramsey’s Method of Separated Oscillating Fields2. The measurement results will be used to test Newtonian Gravity on the 10-16 eV-level. This proposal is part of the joint research project AXION between the Austrian Science Fund FWF (H. Abele, Atominstitut) and the ANR (P. Geltenbort, ILL, ANR-2011-ISO4-007-02), for which an extension proposal will be submitted.
