On some links between quantum physics and gravitation

TL;DR

This paper explores unconventional links between quantum physics and gravity, suggesting that quantum gravity effects may be observable in laboratory settings and proposing new theoretical connections involving gravitons and quantum statistics.

Contribution

It introduces novel ideas connecting quantum phenomena like the Hong-Ou-Mandel effect and quantum statistics to gravity, challenging the notion that quantum gravity effects are only relevant at Planck-scale distances.

Findings

Quantum gravity effects may be detectable in laboratory experiments.

The Hong-Ou-Mandel effect has a relation to quantum gravity.

Existence of gravitons is linked to quantum statistics, predicting a family of high-spin massless particles.

Abstract

It is widely believed that quantum gravity effects are negligible in a conventional laboratory experiment because quantum gravity should play its role only at a distance of about Planck's length ($\sim10^{-33}$ cm). Sometimes that is not the case as shown in this article. We discuss two new ideas about quantum physics connections with gravity. First, the Hong-Ou-Mandel effect relation to quantum gravity is examined. Second, it is shown that the very existence of gravitons is a consequence of quantum statistics. Moreover, since the Bose-Einstein statistics is a special case of Compound Poisson Distribution, it predicts the existence of an infinite family of high-spin massless particles.
