Schrödinger Equation for a Non-Relativistic Particle in a Gravitational Field confined by Two Vibrating Mirrors
Mario Pitschmann, Hartmut Abele
We derive approximate analytical solutions for a particle in a homogenous gravitational field and confined between two independently vibrating mirrors. This constitutes an extensio…
Limit on the Fierz Interference Term b from a Measurement of the Beta Asymmetry in Neutron Decay
Heiko Saul, Christoph Roick, Hartmut Abele +7
In the standard model of particle physics, the weak interaction is described by vector and axial-vector couplings only. Non-zero scalar or tensor interactions would imply an additi…
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…
NoMoS: An Drift Momentum Spectrometer for Beta Decay Studies
Daniel Moser, Hartmut Abele, Joachim Bosina +5
The beta decay of the free neutron provides several probes to test the Standard Model of particle physics as well as to search for extensions thereof. Hence, multiple experiments i…
Design of the Magnet System of the Neutron Decay Facility PERC
Xiangzun Wang, Carmen Ziener, Hartmut Abele +27
The PERC (Proton and Electron Radiation Channel) facility is currently under construction at the research reactor FRM II, Garching. It will serve as an intense and clean source of…
Undetected Electron Backscattering in PERKEO III
Christoph Roick, Heiko Saul, Hartmut Abele +1
The beta asymmetry in neutron beta decay is used to determine the ratio of axial-vector coupling to vector coupling most precisely. In electron spectroscopy, backscattering of elec…
Prospects for Searching Thermal Effects, Non-Newtonian Gravity and Axion-Like Particles: Cannex Test of the Quantum Vacuum
Galina L. Klimchitskaya, Vladimir M. Mostepanenko, René I. P. Sedmik +1
We consider the CANNEX (Casimir And Non-Newtonian force EXperiment) test of the quantum vacuum intended for measuring the gradient of the Casimir pressure between two flat parallel…
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…
