Compaction function in stochastic inflation: a \texttt{FOREST} of type I and II primordial black holes
Chiara Animali, Pierre Auclair, Baptiste Blachier +2
We show how to compute the compaction function within stochastic inflation, by solving the random field dynamics on stochastic binary trees. In this framework, the compaction funct…
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…
Harvesting primordial black holes from stochastic trees with
Chiara Animali, Pierre Auclair, Baptiste Blachier +1
We introduce a novel framework to implement stochastic inflation on stochastic trees, modelling the inflationary expansion as a branching process. Combined with the formalism,…
Clustering of primordial black holes from quantum diffusion during inflation
Chiara Animali, Vincent Vennin
We study how large fluctuations are spatially correlated in the presence of quantum diffusion during inflation. This is done by computing real-space correlation functions in the st…
Primordial black holes from stochastic tunnelling
Chiara Animali, Vincent Vennin
If the inflaton gets trapped in a local minimum of its potential shortly before the end of inflation, it escapes by building up quantum fluctuations in a process known as stochasti…
On Adiabatic Renormalization with a Physically Motivated Infrared Cut-Off
Chiara Animali, Pietro Conzinu, Giovanni Marozzi
We introduce a new approach to renormalize physical quantities in curved space-time by adiabatic subtraction. We use a comoving infrared cut-off in defining the adiabatic counterpa…
