Thin and thick bubble walls III: wall energy
Ariel Mégevand, Federico Agustín Membiela
We study the energy-momentum tensor of a bubble wall beyond the approximation of an infinitely thin wall. To this end, we discuss the proper decomposition into wall and bulk contri…
Thin and thick bubble walls II: expansion in the wall width
Ariel Mégevand, Federico Agustín Membiela
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 approximati…
Thin and thick bubble walls I: vacuum phase transitions
Ariel Mégevand, Federico Agustín Membiela
This is the first in a series of papers where we study the dynamics of a bubble wall beyond usual approximations, such as the assumptions of spherical bubbles and infinitely thin w…
Gravitational waves from bubble walls
Ariel Megevand, Federico Agustin Membiela
We present a general method for computing the gravitational radiation arising from the motion of bubble walls or thin fluid shells in cosmological phase transitions. We discuss the…
Model-independent features of gravitational waves from bubble collisions
Ariel Megevand, Agustin Membiela
We study the gravitational radiation produced by the collisions of bubble walls or thin fluid shells in cosmological phase transitions. Using the so-called envelope approximation,…
Bubble wall correlations in cosmological phase transitions
Ariel Megevand, Federico Agustin Membiela
We study statistical relationships between bubble walls in cosmological first-order phase transitions. We consider the conditional and joint probabilities for different points on t…
