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…

Light and Slow-Neutron Diffraction by Nanodiamond-Dispersed Nanocomposite Holographic Gratings

Y. Tomita, A. Kageyama, Y. Iso +9

We demonstrate the use of nanodiamond in constructing holographic nanoparticle-polymer composite transmission gratings with large saturated refractive index modulation amplitudes a…

Happy Birthday, Ultra-Cold Neutron!

Hartmut Abele, Tobias Jenke, Hartmut Lemmel

What is driving the accelerated expansion of the universe and do we have an alternative for Einstein's cosmological constant? What is dark matter made of? Do extra dimensions of sp…

Proof of Principle for Ramsey-type Gravity Resonance Spectroscopy with qBounce

René I. P. Sedmik, Joachim Bosina, Lukas Achatz +10

Ultracold neutrons (UCNs) are formidable probes in precision tests of gravity. With their negligible electric charge, dielectric moment, and polarizability they naturally evade som…

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…

Multifold paths of neutrons in the three-beam interferometer detected by tiny energy-kick

Hermann Geppert-Kleinrath, Tobias Denkmayr, Stephan Sponar +3

A neutron optical experiment is presented to investigate the paths taken by neutrons in a three-beam interferometer. In various beam-paths of the interferometer, the energy of the…
