Spectrum of Gravitational Waves in Krein Space Quantization (1202.4975v1)

Published 22 Feb 2012 in gr-qc

Abstract: The main goal of this paper is to derive the primordial power spectrum for the scalar perturbations generated as a result of quantum fluctuations during an inflationary pe- riod by an alternative approach of field quantization[1-3]. Formulas are derived for the gravitational waves, special cases of which include power law inflation and inflation in the slow roll approximation, in Krein space quantization.
