Smoking-gun Signatures of Bounce Cosmology from Echoes of Relic Gravitational Waves
We report a novel feature of relic gravitational waves (GWs) in nonsingular bounce cosmologies that is testable in light of GW astronomy. In nonsingular bounce cosmologies, the effective potential ${M}_{p}^{2}{a}^{{\prime\prime} }/a$ that governs the evolution of primordial GWs contains two peaks du...
