On the Detectability of Relic (Squeezed) Gravitational Waves

TL;DR

This paper explores the potential for the first-generation sensitive gravity-wave detectors to detect relic squeezed gravitational waves, focusing on their amplitudes, spectral slopes, and unique correlation properties.

Contribution

It analyzes the detectability of relic squeezed gravitational waves using existing detectors, emphasizing their spectral and correlation features.

Findings

Relic squeezed gravitational waves have detectable amplitudes with current detectors.

Spectral slopes and correlation properties are key indicators for detection.

First-generation detectors could potentially observe these primordial signals.

Abstract

The expected amplitudes and spectral slopes of relic gravitational waves, plus their specific correlation properties associated with the phenomenon of squeezing, may allow the registration of relic (squeezed) gravitational waves by the first generation of sensitive gravity-wave detectors.
