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…
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…
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…
Vanilla Inflation Predicts Negative Running
Jerome Martin, Christophe Ringeval, Vincent Vennin
We show that the simplest, and currently favoured, theoretical realizations of cosmic inflation yield a sharp prediction for the running of the spectral index . Usin…
