Space-time correlations in inflationary spectra, a wave packet analysis
David Campo, Renaud Parentani
The inflationary mechanism of mode amplification predicts that the state of each mode with a given wave vector is correlated to that of its partner mode with the opposite vector. T…
Propagation in a thermal graviton background
Daniel Arteaga, Renaud Parentani, Enric Verdaguer
It is well known that radiative corrections evaluated in nontrivial backgrounds lead to effective dispersion relations which are not Lorentz invariant. Since gravitational interact…
Horizon Entropy
Ted Jacobson, Renaud Parentani
Although the laws of thermodynamics are well established for black hole horizons, much less has been said in the literature to support the extension of these laws to more general s…
Space-time correlations within pairs produced during inflation, a wave-packet analysis
David Campo, Renaud Parentani
In homogeneous universes the propagation of quantum fields gives rise to pair creation of quanta with opposite momenta. When computing expectation values of operators, the correlat…
