On the Gravitational Precession Memory Effect for an Ensemble of Gyroscopes

TL;DR

This paper explores how a group of gyroscopes can detect gravitational waves through thermodynamic changes caused by the gravitational precession memory effect, offering a novel detection method.

Contribution

It introduces the concept of a GravoThermo memory effect, linking gravitational wave passage to thermodynamic changes in gyroscopes, a new approach for gravitational wave detection.

Findings

Thermodynamic quantities of gyroscopes change after gravitational wave passage

The GravoThermo memory effect can serve as a gravitational wave detection method

The study provides a theoretical framework for the effect's application in astrophysics

Abstract

We study the thermodynamic properties of a freely falling ensemble of gyroscopes after the passage of a weak gravitational wave. Due to the precession memory effect, the thermodynamic quantities will experience a change because of the space-time perturbation. We discuss that this GravoThermo memory effect potentially can be used for the detection of the gravitational waves.
