Detecting mirror matter on Earth via its thermal imprint on ordinary matter

TL;DR

This paper proposes a method to detect mirror matter on Earth by observing its cooling effect on ordinary matter, which could help locate hidden dark matter deposits.

Contribution

It introduces a quantitative approach to detect mirror matter through thermal imprint analysis, combining it with centrifuge techniques for improved detection.

Findings

Mirror matter can cause measurable cooling effects in ordinary matter.

The proposed method can potentially identify mirror matter deposits on Earth.

Combining thermal detection with centrifuge techniques enhances detection sensitivity.

Abstract

Mirror matter type dark matter can exist on the Earth's surface, potentially in enhanced concentrations at various anomalous impact sites. Mirror matter fragments can draw in heat from the ordinary matter environment, radiate mirror photons and thereby cool the surrounding ordinary matter. We quantify this effect and suggest that it could be used to help locate mirror matter deposits. This method, together with the centrifuge technique, seems to provide the most promising means to experimentally detect mirror matter type dark matter in the Earth.
