Non Gaussianities from Quantum Decoherence during Inflation
Jerome Martin, Vincent Vennin
Inflationary cosmological perturbations of quantum-mechanical origin generically interact with all degrees of freedom present in the early Universe. Therefore, they must be viewed…
Tunneling in Stochastic Inflation
Mahdiyar Noorbala, Vincent Vennin, Hooshyar Assadullahi +2
The relative probability to decay towards different vacua during inflation is studied. The calculation is performed in single-field slow-roll potentials using the stochastic inflat…
The attractive behaviour of ultra-slow-roll inflation
Chris Pattison, Vincent Vennin, Hooshyar Assadullahi +1
It is often claimed that the ultra-slow-roll regime of inflation, where the dynamics of the inflaton field are friction dominated, is a non-attractor and/or transient. In this work…
The decisive future of inflation
Robert J. Hardwick, Vincent Vennin, David Wands
How much more will we learn about single-field inflationary models in the future? We address this question in the context of Bayesian design and information theory. We develop a no…
