Effects of a Pre-inflationary de Sitter Bounce on the Primordial Gravitational Waves in Gravity Theories
V. K. Oikonomou
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…

A Panorama of Viable Gravity Dark Energy Models
V. K. Oikonomou, Ifigeneia Giannakoudi
In this work we shall study the late-time dynamics of several gravity models. By appropriately expressing the field equations in terms of the redshift and of a statefinder f…

Quantum Corrected Scalar Field Inflation
V. K. Oikonomou, Ifigeneia Giannakoudi
String theory enjoys an elevated role among quantum gravity theories, since it seems to be the most consistent UV completion of general relativity and the Standard Model. However,…
