Acoustic Rabi oscillations between gravitational quantum states and impact on symmetron dark energy
Gunther Cronenberg, Philippe Brax, Hanno Filter +6
The standard model of cosmology provides a robust description of the evolution of the universe. Nevertheless, the small magnitude of the vacuum energy is troubling from a theoretic…
Exact Solution for Chameleon Field, Self-Coupled Through the Ratra-Peebles Potential with n = 1 and Confined Between Two Parallel Plates
A. N. Ivanov, G. Cronenberg, R. Höllwieser +4
We calculate the chameleon field profile, confined between two parallel plates, filled with air at pressure and room temperature and separated by the dist…
Casimir-Polder interaction of neutrons with metal or dielectric surfaces
Valentin Gebhart, Juliane Klatt, Gunther Cronenberg +2
We predict a repulsive Casimir-Polder-type dispersion interaction between a single neutron and a metal or dielectric surface. We consider a scenario where a single neutron is subje…
A Gravity of Earth Measurement with a qBOUNCE Experiment
G. Cronenberg, H. Filter, M. Thalhammer +3
We report a measurement of the local acceleration with ultracold neutrons based on quantum states in the gravity potential of the Earth. The new method uses resonant transition…
Gravity experiments with ultracold neutrons and the qBounce experiment
T. Jenke, G. Cronenberg, M. Thalhammer +3
This work focuses on the control and understanding of a gravitationally interacting elementary quantum system. It offers a new way of looking at gravitation based on quantum interf…
Gravity Resonance Spectroscopy Constrains Dark Energy and Dark Matter Scenarios
T. Jenke, G. Cronenberg, J. Burgdörfer +9
We report on precision resonance spectroscopy measurements of quantum states of ultracold neutrons confined above the surface of a horizontal mirror by the gravity potential of the…
Vectorial velocity filter for ultracold neutrons based on a surface-disordered mirror system
L. A. Chizhova, S. Rotter, T. Jenke +5
We perform classical three-dimensional Monte Carlo simulations of ultracold neutrons scattering through an absorbing-reflecting mirror system in the Earth's gravitational field. We…
A quantized frequency reference in the short-ranged gravity potential and its application for dark matter and dark energy searches
T. Jenke, G. Cronenberg, P. Geltenbort +6
The evidence for the observation of the Higgs spin-0-boson as a manifestation of a scalar field provides the missing corner stone for the standard model of particles (SM). However,…
Heralded generation of entangled photon pairs
Stefanie Barz, Gunther Cronenberg, Anton Zeilinger +1
Entangled photons are a crucial resource for quantum communication and linear optical quantum computation. Unfortunately, the applicability of many photon-based schemes is limited…
