TL;DR

This paper investigates how large extra dimensions could influence gravity-driven quantum state reduction, proposing that superposition collapse times could serve as a new method to probe extra dimensions.

Contribution

It provides order-of-magnitude estimates for nucleon superpositions within the ADD scenario, linking quantum collapse mechanisms to constraints on extra dimensions.

Findings

Potential for superposition experiments to probe extra dimensions

Analysis of time-dependent gravitational constants on collapse mechanisms

Abstract

A gravity-driven mechanism (``objective reduction'') proposed to explain quantum state reduction is analyzed in light of the possible existence of large extra dimensions in the ADD scenario. By calculating order-of-magnitude estimates for nucleon superpositions, it is shown that if the mechanism at question is correct, constraints may be placed on the number and size of extra dimensions. Hence, measurement of superposition collapse times ({\it e.g.} through diffraction or reflection experiments) could represent a new probe of extra dimensions. The influence of a time-dependent gravitational constant on the gravity-driven collapse scheme with and without the presence of extra dimensions is also discussed.
