Thin and thick bubble walls II: expansion in the wall width
arXiv:2401.03102 · doi:10.1088/1475-7516/2024/04/003
Abstract
We study the dynamics of a cosmological bubble wall beyond the approximation of an infinitely thin wall. In a previous paper, we discussed the range of validity of this approximation and estimated the first-order corrections due to the finite width. Here, we introduce a systematic method to obtain the wall equation of motion and its profile at each order in the wall width. We discuss in detail the next-to-next-to-leading-order terms. We use the results to treat the growth of spherical bubbles and the evolution of small deformations of planar walls.
