Inflation with an extra light scalar field after Planck
Vincent Vennin, Kazuya Koyama, David Wands
Bayesian inference techniques are used to investigate situations where an additional light scalar field is present during inflation and reheating. This includes (but is not limited…
Quantum Discord of Cosmic Inflation: Can we Show that CMB Anisotropies are of Quantum-Mechanical Origin?
Jerome Martin, Vincent Vennin
We investigate the quantumness of primordial cosmological fluctuations and its detectability. The quantum discord of inflationary perturbations is calculated for an arbitrary split…
Encyclopaedia Curvatonis
Vincent Vennin, Kazuya Koyama, David Wands
We investigate whether the predictions of single-field models of inflation are robust under the introduction of additional scalar degrees of freedom, and whether these extra fields…
The Hubble Flow of Plateau Inflation
Dries Coone, Diederik Roest, Vincent Vennin
In the absence of CMB precision measurements, a Taylor expansion has often been invoked to parametrize the Hubble flow function during inflation. The standard "horizon flow" proced…
Correlation Functions in Stochastic Inflation
Vincent Vennin, Alexei A. Starobinsky
Combining the stochastic and formalisms, we derive non perturbative analytical expressions for all correlation functions of scalar perturbations in single-field, slow-roll inf…
