Gravity Resonance Spectroscopy constrains Dark Matter and Dark Energy Scenarios

PTB - Kolloquium

This talk focuses on the control and understanding of a gravitationally interacting elementary quantum system using the techniques of resonance spectroscopy. It offers a new way of looking at gravitation based on quantum interference. The ultra-cold neutron reflects from a mirror in well-defined quantum states in the gravity potential of the earth allowing to apply the concept of gravity resonance spectroscopy (GRS). GRS relies on frequency measurements, which provide a spectacular sensitivity.

Our team at TU Wien is working on an analysis of the Standard Model of Particle Physics and Gravitation, where the neutron is the object. We plan to provide a universal look at gravitation. The neutron gives access to all parameters: distance, mass, curvature, energy-momentum tensor, and torsion.

We present limits on dark energy and dark matter candidates [Jen14].
