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…
Primordial black holes in excursion set theory: Formation probabilities, mass functions, and window functions
Hayami Iizuka, Daiki Saito, Koki Tokeshi
We study the mass function of primordial black holes (PBHs) within the excursion-set theory, in which the response of the stochastic density contrast to the variation of the coarse…
Multifield stochastic inflation: Relevance of number of fields in statistical moments
Tomo Takahashi, Koki Tokeshi
In multifield inflation driven by scalar fields, symmetry renders the number of fields irrelevant at classical level. This ceases to be the case once stochastic effects…
Primordial black holes and smooth coarse-graining in excursion set theory
Daiki Saito, Koki Tokeshi
The excursion-set formalism enables us to infer the mass distribution of collapsed objects, such as primordial black holes (PBHs), by the language of stochastic processes. Within t…
