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… read more here.

Abstract: 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 contributions, and we use a systematic… read more here.
