Quantum and thermal pressures from light scalar fields
Hauke Fischer, Christian Käding, Mario Pitschmann
Light scalar fields play a variety of roles in modern physics, especially in cosmology and modified theories of gravity. For this reason, there is a zoo of experiments actively try…
Search for dark energy with neutron interferometry
Hauke Fischer, Christian Käding, Hartmut Lemmel +2
We use previously obtained experimental results by neutron interferometry to effectively constrain the parameter space of several prominent dark energy models. This investigation e…
Dilaton-induced open quantum dynamics
Christian Käding, Mario Pitschmann, Caroline Voith
In modern cosmology, scalar fields with screening mechanisms are often used as explanations for phenomena like dark energy or dark matter. Amongst a zoo of models, the environment…
Gravity Resonance Spectroscopy and Dark Energy Symmetron Fields
Tobias Jenke, Joachim Bosina, Jakob Micko +3
Spectroscopic methods allow to measure energy differences with unrivaled precision. In the case of gravity resonance spectroscopy, energy differences of different gravitational sta…
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…
Neutron Interferometry constrains dark energy chameleon fields
H. Lemmel, Ph. Brax, A. N. Ivanov +7
We present phase shift measurements for neutron matter waves in vacuum and in low pressure Helium using a method originally developed for neutron scattering length measurements in…
