Dynamics of nucleation in thermal phase transitions
Oliver Gould, Joonas Hirvonen, Andrey Shkerin +1
We study dynamical effects during nucleation in thermal first-order phase transitions in field theory. Focusing on the classical regime of the decay of a metastable state, we prese…
Quantum field nucleating and Wigner functions
Joonas Hirvonen
We present a novel real-time framework for the decay of metastable states in quantum field theories using Wigner functions. The framework introduces a nonperturbative nucleation ra…
WallGo investigates: Theoretical uncertainties in the bubble wall velocity
Jorinde van de Vis, Philipp Schicho, Lauri Niemi +3
We examine theoretical uncertainties in state-of-the-art calculations of the bubble wall velocity during first-order cosmological phase transitions. By utilising the software WallG…
Langer's nucleation rate reproduced on the lattice
Joonas Hirvonen, Oliver Gould
We show that Langer's rate of bubble nucleation is quantitatively correct up to small higher-loop corrections, in comparison to lattice simulations. These results are a significant…
How fast does the WallGo? A package for computing wall velocities in first-order phase transitions
Andreas Ekstedt, Oliver Gould, Joonas Hirvonen +4
WallGo is an open source software for the computation of the bubble wall velocity in first-order cosmological phase transitions. It also computes the energy budget available for th…
Real-Time Nucleation and Off-Equilibrium Effects in High-Temperature Quantum Field Theories
Joonas Hirvonen
We study real-time nucleation in perturbative high-temperature quantum field theories. Specifically, we incorporate the evolution of thermally fluctuating plasma driven out of equi…
Computing the gauge-invariant bubble nucleation rate in finite temperature effective field theory
Joonas Hirvonen, Johan Löfgren, Michael J. Ramsey-Musolf +2
A gauge-invariant framework for computing bubble nucleation rates at finite temperature in the presence of radiative barriers was presented and advocated for model-building and phe…
