TLDR
In this paper, the authors use a Green's function approach to calculate the tunneling rate between radiatively generated non-degenerate vacua, and apply this to a model that exhibits spontaneous symmetry breaking via the Coleman-Weinberg mechanism.Abstract:
We use a Green’s function approach in order to develop a method for calculating the tunneling rate between radiatively generated nondegenerate vacua. We apply this to a model that exhibits spontaneous symmetry breaking via the Coleman-Weinberg mechanism, where we determine the self-consistent tunneling configuration and illustrate the impact of gradient effects that arise from accounting for the underlying space-time inhomogeneity.read more

Cosmic phase transitions: their applications and experimental signatures
Anupam Mazumdar,Graham White +1 more
TL;DR: In this article, the authors review different types of phase transitions that can appear in our cosmic history, and their applications and experimental signatures in particular in the context of exciting gravitational waves, which could be potentially be constrained by LIGO/VIRGO, Kagra, and eLISA.

Theoretical uncertainties for cosmological first-order phase transitions
Djuna Croon,Oliver Gould,Philipp Schicho,Philipp Schicho,Tuomas V. I. Tenkanen,Graham White,Graham White +6 more
TL;DR: In this paper, the authors examine the magnitude of theoretical uncertainties in perturbative calculations of fist-order phase transitions, using the Standard Model effective field theory as their guide, and find large uncertainties due to renormalization scale dependence, which amount to two to three orders of magnitude uncertainty in the peak gravitational wave amplitude, relevant to experiments such as LISA.
