Generating Gravitational Waves After Inflation
arXiv:0906.4527 · doi:10.1016/j.nuclphysbps.2009.07.035
Abstract
I review two mechanisms by which gravitational waves can be generated at the end of inflation: preheating, and gravitons Hawking radiated during the decay of very small primordial black holes. These mechanisms are contrasted with the gravitational waves during inflation, and may provide a window into the physical processes that govern the end of the inflationary phase.
