Time-reversed stochastic inflation in the quantum well
Chiara Animali, Baptiste Blachier, Nanoka Okada +3
Time-reversed stochastic inflation solves the stochastic evolution of the inflationary universe backward in time, by counting the number of e-folds from the end of quantum diffusio…
Comment on: "Third-order corrections to the slow-roll expansion: Calculation and constraints with Planck, ACT, SPT, and BICEP/Keck [2025 PDU 47 101813]"
Pierre Auclair, Christophe Ringeval
We point out that several terms in the third-order corrections to the slow-roll power spectra presented by Ballardini et al. [1] are incorrect. The authors of that work claim that…
Friction in Stochastic Inflation
Baptiste Blachier, Christophe Ringeval
We solve time-reversed stochastic inflation in the semi-infinite flat potential with a constant drift term and derive an exact expression for the probability distribution of the cu…
BaBy Cosmic Tension
Christophe Ringeval
We show that the recently released B-mode polarisation data from the South Pole Telescope (SPT) favour a non-vanishing contribution of primordial gravitational waves of inflationar…
Time-reversed Stochastic Inflation
Baptiste Blachier, Christophe Ringeval
Cosmic inflation may exhibit stochastic periods during which quantum fluctuations dominate over the semi-classical evolution. Extracting observables in these regimes is a notorious…
Clocking the End of Cosmic Inflation
Pierre Auclair, Baptiste Blachier, Christophe Ringeval
Making observable predictions for cosmic inflation requires determining when the wavenumbers of astrophysical interest today exited the Hubble radius during the inflationary epoch.…
