Observation of a magnetic shift in neutron whispering-gallery states
K. Schreiner, J. A. Pioquinto, S. Baeßler +19
We developed experimental and theoretical methods to create and describe high-resolution whispering-gallery interference patterns and show the feasibility of measuring their small…
Gravitational and other shifts of whispering gallery and gravitational state interference patterns of light neutral particles
V. V. Nesvizhevsky, J. A. Pioquinto, K. Schreiner +7
We discuss small shifts in the interference patterns of gravitational and whispering gallery quantum states that can be observed with neutrons, atoms, antiatoms, muonium, positroni…
GRASIAN: Shaping and characterization of the cold hydrogen and deuterium beams for the forthcoming first demonstration of gravitational quantum states of atoms
Carina Killian, Philipp Blumer, Paolo Crivelli +9
A low energy particle confined by a horizontal reflective surface and gravity settles in gravitationally bound quantum states. These gravitational quantum states (GQS) were so far…
Positron production using a 9 MeV electron linac for the GBAR experiment
M. Charlton, J. J. Choi, M. Chung +67
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses…
Exploring gravity with the MIGA large scale atom interferometer
B. Canuel, A. Bertoldi, L. Amand +22
We present an underground long baseline atom interferometer to study gravity at large scale. The hybrid atom-laser antenna will use several atom interferometers simultaneously inte…
Temperature dependence of the probability of "small heating" and spectrum of UCNs up-scattered on the surface of Fomblin oil Y-HVAC 18/8
V. V. Nesvizhevsky, A. Yu. Voronin, A. Lambrecht +5
We performed precision measurements of the probability of small heating and spectrum of UCNs up-scattered on the surface of hydrogen-free oil Fomblin Y-HVAC 18/8 as a function of t…
Quenching of antihydrogen gravitational states by surface charges
A. Yu. Voronin, E. A. Kupriyanova, A. Lambrecht +2
We study an effect of quenching of antihydrogen quantum states near material surface in the gravitational field of the Earth by local charges randomly distributed along the mirror…
Quantum ballistic experiment on antihydrogen fall
A. Yu. Voronin, V. V. Nesvizhevsky, G. Dufour +1
We study an interferometric approach to measure gravitational mass of antihydrogen. The method consists of preparing a coherent superposition of antihydrogen quantum state localize…
Quantum reflection and Liouville transformations from wells to walls
Gabriel Dufour, Romain Guérout, Astrid Lambrecht +1
Liouville transformations map in a rigorous manner one Schrödinger equation into another, with a changed scattering potential. They are used here to transform quantum reflection of…
A spectroscopy approach to measure the gravitational mass of antihydrogen
A. Yu. Voronin, V. V. Nesvizhevsky, G. Dufour +6
We study a method to induce resonant transitions between antihydrogen () quantum states above a material surface in the gravitational field of the Earth. The method consis…
Study of levitating nanoparticles using ultracold neutrons
V. V. Nesvizhevsky, A. Yu. Voronin, A. Lambrecht +1
Physical adsorption of atoms, molecules and clusters on surface is known. It is linked to many phenomena in physics, chemistry, and biology. Usually the studies of adsorption are l…
Whispering Gallery States of Antihydrogen
A. Yu. Voronin, V. V. Nesvizhevsky, S. Reynaud
We study theoretically interference of the long-living quasistationary quantum states of antihydrogen atoms, localized near a concave material surface. Such states are an antimatte…
