Experimental test of symmetron-field based dark energy model using neutron interferometry
Andreas Dvorak, Kazuma Obigane, Hartmut Lemmel +2
We report phase shift measurements of neutron matter waves propagating in vacuum and low-pressure Argon gas, using a technique developed for neutron interferometric scattering leng…
A search for neutron-to-hidden-neutron oscillations in a ultra-cold neutron beam
G. Ban, J. Chen, P. -J. Chiu +11
Models that postulate the existence of hidden sectors address contemporary questions, such as the source of baryogenesis and the nature of dark matter. Among the possible mixing pr…
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…
Spectroscopy with cold and ultra-cold neutrons
Hartmut Abele, Tobias Jenke, Gertrud Konrad
We present two new types of spectroscopy methods for cold and ultra-cold neutrons. The first method, which uses the \RB drift effect to disperse charged particles in a uniformly cu…
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…
