TL;DR
This paper investigates how stochastic gravitational waves cause decoherence in macroscopic systems, highlighting that gravitational scattering dominates decoherence due to the high effective temperature of the galactic gravitational wave background.
Contribution
It introduces a detailed analysis of gravitational wave-induced decoherence, emphasizing the dominant role of gravitational scattering over damping in macroscopic systems.
Findings
Gravitational scattering is the main source of decoherence for planetary systems.
The high effective temperature of galactic gravitational waves enhances decoherence effects.
Decoherence occurs without significant damping influence.
Abstract
We study the decoherence process associated with the scattering of stochastic gravitational waves. We discuss the case of macroscopic systems, such as the planetary motion of the Moon around the Earth, for which gravitational scattering is found to dominate decoherence though it has a negligible influence on damping. This contrast is due to the very high effective temperature of the background of gravitational waves in our galactic environment.
