Effects of a pre-inflationary de Sitter bounce on the primordial gravitational waves in f(R) gravity theories
In this work we examine the effects of a pre-inflationary de Sitter bounce on the energy spectrum of the primordial gravitational waves. Specifically we assume that the Universe is described by several evolution patches, starting with a de Sitter pre-inflationary bounce which is followed by an quasi...
