Generalized Boundary Conditions for the qBounce Experiment
Eric J. Sung, Benjamin Koch, Tobias Jenke +2
Discrepancies between theory and recent qBounce data have prompted renewed scrutiny of how boundary conditions are implemented for ultracold neutrons bouncing above a mirror in Ear…
Very Special Relativity in Accelerated Frames: Non-relativistic Effects in Gravitational Spectroscopy of Ultracold Neutrons
Alessandro Santoni, Enrique Muñoz, Hartmut Abele +1
In this paper, we investigate the phenomenology of fermionic systems in uniform gravitational fields within the framework of Very Special Relativity (VSR). We focus on the case of…
Gravitational waves in scalar-tensor theory to one-and-a-half post-Newtonian order
David Trestini
We compute the gravitational waves generated by compact binary systems in a class of massless scalar-tensor (ST) theories to the 1.5 post-Newtonian (1.5PN) order beyond the standar…
qBounce: Systematic shifts of transition frequencies of gravitational states of ultra-cold neutrons using Ramsey gravity resonance spectroscopy
Jakob Micko, J. Bosina, S. S. Cranganore +5
qBounce is using quantum states of ultra-cold neutrons in the gravitational field of the Earth to investigate gravitation in the micrometre range. We present current measurements t…
UGR tests with atomic clocks and atom interferometers
Fabio Di Pumpo
Atomic interference experiments test the universality of the coupling between matter-energy and gravity at different spacetime points, thus being in principle able to probe possibl…
Gravitational waves in scalar-tensor theory to one-and-a-half post-Newtonian order
Laura Bernard, Luc Blanchet, David Trestini
We compute the gravitational waves generated by compact binary systems in a class of massless scalar-tensor (ST) theories to the 1.5 post-Newtonian (1.5PN) order beyond the standar…
A Novel Nuclear Emulsion Detector for Measurement of Quantum States of Ultracold Neutrons in the Earth's Gravitational Field
Naoto Muto, Hartmut Abele, Tomoko Ariga +19
Hypothetical short-range interactions could be detected by measuring the wavefunctions of ultracold neutrons (UCNs) on a mirror bounded by the Earth's gravitational field. The Sear…
A Gravity of Earth Measurement with a qBOUNCE Experiment
G. Cronenberg, H. Filter, M. Thalhammer +3
We report a measurement of the local acceleration with ultracold neutrons based on quantum states in the gravity potential of the Earth. The new method uses resonant transition…
Gravity experiments with ultracold neutrons and the qBounce experiment
T. Jenke, G. Cronenberg, M. Thalhammer +3
This work focuses on the control and understanding of a gravitationally interacting elementary quantum system. It offers a new way of looking at gravitation based on quantum interf…
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…
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…
The influence of the chameleon field potential on transition frequencies of gravitationally bound quantum states of ultra-cold neutrons
A. N. Ivanov, R. Höllwieser, T. Jenke +2
We calculate the chameleon field potential for ultracold neutrons, bouncing on top of one or between two neutron mirrors in the gravitational field of the Earth. For the resulting…
Ramsey's Method of Separated Oscillating Fields and its Application to Gravitationally Induced Quantum Phaseshifts
H. Abele, T. Jenke, H. Leeb +1
We propose to apply Ramsey's method of separated oscillating fields to the spectroscopy of the quantum states in the gravity potential above a vertical mirror. This method allows a…
