We present a general numerical method for computing precisely the false vacuum decay rate, including the prefactor due to quantum fluctuations about the classical bounce solution, in a self-interacting scalar field theory modeling the process of nucleation in four-dimensional space-time. This technique does not rely on the thin-wall approximation. The method is based on the Gelfand-Yaglom approach to determinants of differential operators, suitably extended to higher dimensions using angular…

On the prefactor in false vacuum decay

This paper gives a survey of recent work in collaboration with G Dunne concerning a new method for computing determinants in quantum field-theoretic applications, using angular momentum cut-off

NNLO corrections to false vacuum decay rate in thin-wall approximation

Recently it was discovered that the Standard Model vacuum may suffer an essential metastability near the Planck scale. In this regard it makes sense to study in more detail the decay processes of the

Analytic thin wall false vacuum decay rate

We derive a closed-form false vacuum decay rate at one loop in the thin wall limit, where the true and false vacua are nearly degenerate. We obtain the bounce configuration in D dimensions, together

Functional methods for false-vacuum decay in real time

We present the calculation of the Feynman path integral in real time for tunneling in quantum mechanics and field theory, including the first quantum corrections. For this purpose, we use the

Quantum and gradient corrections to false vacuum decay on a de Sitter background

We study the effects of a fixed de Sitter geometry background in scenarios of false vacuum decay. It is currently understood that bubble nucleation processes associated with first order phase

Fast way to compute functional determinants of radially symmetric partial differential operators in general dimensions

Recently the partial-wave cutoff method was developed as a new calculational scheme for a functional determinant of quantum field theory in radial backgrounds. For the contribution given by an

Thin-wall approximation in vacuum decay: A lemma

The ``thin-wall approximation'' gives a simple estimate of the decay rate of an unstable quantum field. Unfortunately, the approximation is uncontrolled. In this paper I show that there are actually

Precision decay rate calculations in quantum field theory

Tunneling in quantum field theory is worth understanding properly, not least because it controls the long term fate of our universe. There are however, a number of features of tunneling rate

A fresh look at the calculation of tunneling actions in multi-field potentials

The quantum decay of a metastable vacuum is exponentially suppressed by a tunneling action that can be calculated in the semi-classical approximation as the Euclidean action of a bounce that

Radiative effects on false vacuum decay in Higgs-Yukawa theory

We derive fermionic Green's functions in the background of the Euclidean solitons describing false vacuum decay in a prototypal Higgs-Yukawa theory. In combination with appropriate counterterms for



False vacuum decay

This thesis reviews the exact numerical computation of the classical bounce solution in the false vacuum decay for a quartic scalar field potential which is offset by an external source. The decay

One loop corrections to the metastable vacuum decay

We evaluate the one-loop prefactor in the false vacuum decay rate in a theory of a self-interacting scalar field in $3+1$ dimensions. We use a numerical method, established some time ago, which is

Calculation of QCD instanton determinant with arbitrary mass

The precise quark mass dependence of the one-loop effective action in an instanton background has recently been computed [Phys. Rev. Lett. 94, 072001 (2005).]. The result interpolates smoothly

The standard bounce formalism for calculating the decay rate of a metastable vacuum cannot be applied to theories in which the symmetry breaking is due to radiative corrections, because in such

The Fate of the False Vacuum. 1. Semiclassical Theory

It is possible for a classical field theory to have two homogeneous stable equilibrium states with different energy densities. In the quantum version of the theory, the state of higher energy density
