[QG-AA] Stochastic gravitational wave background in quantum gravity

by Sachiko Kuroyanagi (IFT Madrid)

Thursday 24 Feb 2022, 17:00 → 19:00 Europe/Berlin

Primordial gravitational waves provide one of the few opportunities for learning the physics of the early universe and for testing quantum gravity. Among all cosmological quantum-gravity or quantum-gravity-inspired scenarios, only very few predict a blue-tilted primordial tensor spectrum. In this talk, first, I will review the potential of future gravitational wave observations to test the early universe. Then, in the second part, I will present the results of my recent paper arXiv:2012.00170 [JCAP 03, 019 (2021)], where we explored quantum-gravity-inspired scenarios and checked whether they can generate a stochastic gravitational-wave background detectable by present and future interferometers.
