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…
