A Simple Signal of Noncommutative Space

TL;DR

This paper proposes a straightforward classical experiment to detect noncommutative space effects at low energies, providing a clear separation from standard physics and establishing a significant bound on the noncommutative scale.

Contribution

It introduces a simple experimental method to identify noncommutative space effects and derives a notable bound on the noncommutative scale with elementary reasoning.

Findings

Established a new bound on the noncommutative scale

Demonstrated a clear separation of noncommutative effects from commutative physics

Proposed a feasible low-energy classical experiment

Abstract

We propose a simple low-energy classical experiment in which the effects of noncommutativity can be clearly separated from commutative physics. The ensuing bound on the noncommutative scale is remarkable, especially in view of its elementary derivation.
