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…
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…
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…
