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…

Damped Corrections to Inflationary Spectra from a Fluctuating Cutoff
David Campo, Jens Niemeyer, Renaud Parentani
We reconsider trans-Planckian corrections to inflationary spectra by taking into account a physical effect which has been overlooked and which could have important consequences. We…
