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…
Impulsively Excited Gravitational Quantum States: Echoes and Time-resolved Spectroscopy
I. Tutunnikov, K. V. Rajitha, A. Yu. Voronin +2
We theoretically study an impulsively excited quantum bouncer (QB) - a particle bouncing off a surface in the presence of gravity. A pair of time-delayed pulsed excitations is show…
Quantum interference test of the equivalence principle on antihydrogen
P. -P. Crépin, C. Christen, R. Guérout +3
We propose to use quantum interferences to improve the accuracy of the measurement of the free fall acceleration g of antihydrogen in the GBAR experiment. This method uses most ant…
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…
Gravitational resonance spectroscopy with an oscillating magnetic field gradient in the GRANIT flow through arrangement
G. Pignol, S. Baessler, V. V. Nesvizhevsky +3
Gravitational resonance spectroscopy consists in measuring the energy spectrum of bouncing ultracold neutrons above a mirror by inducing resonant transitions between different disc…
Quantum Reflection of Antihydrogen in the GBAR Experiment
Gabriel Dufour, Romain Guérout, Astrid Lambrecht +3
In the GBAR experiment, cold antihydrogen atoms will be left to fall on an annihilation plate with the aim of measuring the gravitational acceleration of antimatter. Here, we study…
