Description

Abstract I present a numerical package (CosmoTransitions) for analyzing finite-temperature cosmological phase transitions driven by single or multiple scalar fields. The package analyzes the different vacua of a theory to determine their critical temperatures (where the vacuum energy levels are degenerate), their supercooling temperatures, and the bubble wall profiles which separate the phases and describe their tunneling dynamics. I introduce a new method of path deformation to find the profiles of b... Title of program: CosmoTransitions Catalogue Id: AEML_v1_0 Nature of problem I describe a program to analyze early-Universe finite-temperature phase transitions with multiple scalar fields. The goal is to analyze the phase structure of an input theory, determine the amount of supercooling at each phase transition, and find the bubble-wall profiles of the nucleated bubbles that drive the transitions. Versions of this program held in the CPC repository in Mendeley Data AEML_v1_0; CosmoTransitions; 10.1016/j.cpc.2012.04.004 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
