TL;DR

This paper calculates transition probabilities between energy levels of a quantum bouncer caused by noise-like perturbations, with implications for improving precision in neutron quantum bouncer experiments.

Contribution

It introduces a method to evaluate noise-induced transitions in a quantum bouncer, relevant for experimental setups like the GRANIT neutron experiment.

Findings

Transition probabilities depend on noise characteristics

Vibrations and mirror waviness significantly affect level transitions

Results aid in designing more precise quantum bouncer experiments

Abstract

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 and mirror surface waviness) which might play an important role in future GRANIT experiment, aiming at precision studies of/with the neutron quantum bouncer.
