Minimal decoherence from inflation
C. P. Burgess, R. Holman, Greg Kaplanek +2
We compute the rate with which super-Hubble cosmological fluctuations are decohered during inflation, by their gravitational interactions with unobserved shorter-wavelength scalar…
Comparing quantumness criteria
Jerome Martin, Amaury Micheli, Vincent Vennin
Measuring the quantumness of a system can be done with a variety of methods. In this article we compare different criteria, namely quantum discord, Bell inequality violation and no…
Discord and Decoherence
Jerome Martin, Amaury Micheli, Vincent Vennin
In quantum information theory, quantum discord has been proposed as a tool to characterise the presence of "quantum correlations" between the subparts of a given system. Whether a…
Real-space entanglement in the Cosmic Microwave Background
Jerome Martin, Vincent Vennin
We compute the entanglement entropy, mutual information and quantum discord of the Cosmic Microwave Background (CMB) fluctuations in real space. To that end, we first show that mea…
Real-space entanglement of quantum fields
Jerome Martin, Vincent Vennin
We introduce a new method permitting the analytical determination of entanglement entropy (and related quantities) between configurations of a quantum field, which is either free o…
Opening the reheating box in multifield inflation
Jerome Martin, Lucas Pinol
The robustness of multi-field inflation to the physics of reheating is investigated. In order to carry out this study, reheating is described in detail by means of a formalism whic…
