Quantum recoherence in the early universe
Thomas Colas, Julien Grain, Vincent Vennin
Despite being created through a fundamentally quantum-mechanical process, cosmological structures have not yet revealed any sign of genuine quantum correlations. Among the obstruct…
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…
Non-perturbative non-Gaussianity and primordial black holes
Andrew D. Gow, Hooshyar Assadullahi, Joseph H. P. Jackson +3
We present a non-perturbative method for calculating the abundance of primordial black holes given an arbitrary one-point probability distribution function for the primordial curva…
Primordial black holes from stochastic tunnelling
Chiara Animali, Vincent Vennin
If the inflaton gets trapped in a local minimum of its potential shortly before the end of inflation, it escapes by building up quantum fluctuations in a process known as stochasti…
Benchmarking the cosmological master equations
Thomas Colas, Julien Grain, Vincent Vennin
Master equations are commonly employed in cosmology to model the effect of additional degrees of freedom, treated as an "environment", onto a given "system". However, they rely on…
