Quantenfluktuationen kosmologischer Phasenübergänge: Von Zerfallsraten zur Dynamik expandierender Nukleationsblasen

Year: 2025

Type: dissertation

Abstract: Cosmological phase transitions are potential sources of gravitational waves, motivating precise theory predictions. This thesis develops tools to compute decay rates at next-to-leading order and beyond, consistently incorporating non-local self-energies via the two-particle-irreducible effective action. I further study bubble dynamics within nonequilibrium quantum field theory and establish a unifying framework for phase transitions.
