Universal CMB Phase Coherence from Single-Field Inflation
Siméon Vareilles, Thomas Colas, Julien Grain +2
The phase coherence of primordial perturbations shapes the acoustic peaks of the CMB and is regarded as a key signature of inflation. Inflationary scenarios at different energy sca…
Hidden quantum-informatic symmetries of quasi-de Sitter backgrounds
Suddhasattwa Brahma, Jaime Calderon-Figueroa, Xiancong Luo +1
We investigate how degeneracies in quasi-de Sitter backgrounds, in the sense of Wands' duality, are reflected in real-space quantum correlations of primordial perturbations. Using…
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…
Quantum Stochastic Inflation
Robson Christie, Jaewoo Joo, Greg Kaplanek +2
We formulate stochastic inflation in an open quantum system framework. The field coarse-grained in a patch of fixed physical size, and the total momentum of that patch, form a cano…
Excursion-set for Primordial Black Holes I: white noise and moving barrier
Pierre Auclair, Baptiste Blachier, Vincent Vennin
In the excursion-set formalism, the mass distribution of primordial black holes (PBHs) is derived from the first-passage time of a random walk describing the density contrast as th…
Symmetries of cosmological perturbations: The residual low-multipole ambiguity
Jibril Ben Achour, Etera Livine, Vincent Vennin
In cosmology, long-wavelength modes are related to large-gauge transformations (LGT), i.e. changes of coordinates that modify the physical geometry of the cosmological patch. These…
