Frequency shifts in gravitational resonance spectroscopy
S. Baeßler, V. V. Nesvizhevsky, G. Pignol +4
Quantum states of ultracold neutrons in the gravitational field are to be characterized through gravitational resonance spectroscopy. This paper discusses systematic effects that a…
Transitions between levels of a quantum bouncer induced by a noise-like perturbation
C. Codau, V. V. Nesvizhevsky, M. Fertl +2
The probability of transition between levels of a quantum bouncer, induced by a noise-like perturbation, is calculated. The results are applied to two sources of noise (vibrations…
The GRANIT project: Status and Perspectives
Stephan Baeßler, Alexei Gagarski, Ludmilla Grigorieva +8
The GRANIT project is the follow-up of the pioneering experiments that first observed the quantum states of neutrons trapped in the earth's gravitational field at the Institute Lau…
Quasi-specular albedo of cold neutrons from powder of nanoparticles
R. Cubitt, E. V. Lychagin, A. Yu. Muzychka +5
We predicted and observed for the first time the quasi-specular albedo of cold neutrons at small incidence angles from a powder of nanoparticles. This albedo (reflection) is due to…
Measurement of the neutron electric dipole moment by crystal diffraction
V. V. Fedorov, M. Jentschel, I. A. Kuznetsov +9
An experiment using a prototype setup to search for the neutron electric dipole moment by measuring spin-rotation in a non-centrosymmetric crystal (quartz) was carried out to inves…
Constraints on spin-dependent short-range interactions using gravitational quantum levels of ultracold neutrons
S. Baeßler, V. V. Nesvizhevsky, G. Pignol +2
In this paper, we discuss a possibility to improve constraints on spin-dependent short-range interactions in the range of 1 - 200 micrometer significantly. For such interactions, o…
