Decoherence and entropy of primordial fluctuations. I: Formalism and interpretation
David Campo, Renaud Parentani
We propose an operational definition of the entropy of cosmological perturbations based on a truncation of the hierarchy of Green functions. The value of the entropy is unambiguous…

Decoherence and entropy of primordial fluctuations II. The entropy budget
David Campo, Renaud Parentani
We calculate the entropy of adiabatic perturbations associated with a truncation of the hierarchy of Green functions at the first non trivial level, i.e. in a self-consistent Gauss…

Signatures of trans-Planckian dispersion in inflationary spectra
Jean Macher, Renaud Parentani
The primordial spectra are calculated using dispersion relations which deviate from the relativistic one above a certain energy scale Lambda. We determine the properties of the lea…
