Seeded bubble nucleation on the lattice
Simone Blasi, Andreas Ekstedt, Jaakko Hällfors +1
We provide the first non-perturbative lattice determination of the bubble nucleation rate as seeded by topological defects during a first order phase transition. Our case of study…
Scalar damping in cosmological phase transitions
Andreas Ekstedt, Thomas Konstandin, Jorinde van de Vis
We outline how to calculate the scalar damping term during a cosmological phase transition from kinetic theory. We determine the scalar damping rate from top quarks and weak gauge…
Bubble-wall speed with loop corrections
Andrii Dashko, Andreas Ekstedt
In this paper, we investigate the dynamics of the nucleating scalar field during the first-order phase transitions by incorporating one-loop corrections of classical fluctuations.…
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…
Cosmological phase transitions at three loops: the final verdict on perturbation theory
Andreas Ekstedt, Philipp Schicho, Tuomas V. I. Tenkanen
We complete the perturbative program for equilibrium thermodynamics of cosmological first-order phase transitions by determining the finite-temperature effective potential of gauge…
BubbleDet: A Python package to compute functional determinants for bubble nucleation
Andreas Ekstedt, Oliver Gould, Joonas Hirvonen
We present a Python package, BubbleDet, for computing one-loop functional determinants around spherically symmetric background fields. This gives the next-to-leading order correcti…
