- Title
Geometric back-reaction in pre-inflation from relativistic quantum geometry.
- Authors
Arcodía, Marcos; Bellini, Mauricio
- Abstract
The pre-inflationary evolution of the universe describes the beginning of the expansion from a static initial state, such that the Hubble parameter is initially zero, but increases to an asymptotic constant value, in which it could achieve a de Sitter (inflationary) expansion. The expansion is driven by a background phantom field. The back-reaction effects at this moment should describe vacuum geometrical excitations, which are studied in detail in this work using relativistic quantum geometry.
