Inflaton Fragmentation and Oscillon Formation in Three Dimensions
Mustafa A. Amin, Richard Easther, Hal Finkel
Analytical arguments suggest that a large class of scalar field potentials permit the existence of oscillons -- pseudo-stable, non-topological solitons -- in three spatial dimensio…

PSpectRe: A Pseudo-Spectral Code for (P)reheating
Richard Easther, Hal Finkel, Nathaniel Roth
PSpectRe is a C++ program that uses Fourier-space pseudo-spectral methods to evolve interacting scalar fields in an expanding universe. PSpectRe is optimized for the analysis of pa…
