A Bumpy Start to a Smooth Ride: Onset of Inflation amid Backreaction from Inhomogeneities
Jolyon K. Bloomfield, Patrick Fitzpatrick, Kiriakos Hilbert +1
We analyze the onset of inflation for a simple single-field model when the system begins with significant inhomogeneities on length-scales shorter than the initial Hubble radius. W…
Statistics of Peaks in Chi-Squared Fields
Jolyon K. Bloomfield, Stephen H. P. Face, Alan H. Guth +2
Chi-squared random fields arise naturally from the study of fluctuations in field theories with SO(n) symmetry. The extrema of chi-squared fields are of particular physical interes…
Mass of a Patch of an FRW Universe
Sarah R. Geller, Jolyon K. Bloomfield, Alan H. Guth
In 1963, Zel'dovich devised a method to define the mass of a closed Friedmann-Robertson-Walker (FRW) universe, showing that by this definition it is exactly zero. Rounding out this…
Formalism for Primordial Black Hole Formation in Spherical Symmetry
Jolyon Bloomfield, Daniel Bulhosa, Stephen Face
We present a comprehensive formalism for the description of primordial black hole formation in spherical symmetry based on the formalisms of Misner, Sharp, and Hernandez, which can…
