Gravitational Waves from an Axion-Dark Photon System: A Lattice Study

no code implementations21 Dec 2020 Wolfram Ratzinger, Pedro Schwaller, Ben A. Stefanek

In this work, we present a lattice study of an axion - dark photon system in the early Universe and show that the stochastic gravitational wave (GW) background produced by this system may be probed by future GW experiments across a vast range of frequencies.

Gravitational wave probes of axion-like particles

no code implementations2 Dec 2019 Camila S. Machado, Wolfram Ratzinger, Pedro Schwaller, Ben A. Stefanek

We have recently shown that axions and axion-like particles (ALPs) may emit an observable stochastic gravitational wave (GW) background when they begin to oscillate in the early universe.
