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…

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…
