Fermionic fluctuation corrections to bubble nucleation.
We determine the fermionic corrections to the nucleation rate of bubbles at the electroweak phase transition. The fermion determinant is evaluated exactly and by using the gradient expansion. The gradient expansion is found to be a reliable approximation and is used to extrapolate to the large values of νn = (2n+ 1)πT needed in the Matsubara sum. The contribution to effective action is found to...
متن کاملFluctuation corrections to bubble nucleation.
The fluctuation determinant which determines the preexponential factor of the transition rate for minimal bubbles is computed for the electroweak theory with sinΘW = 0. As the basic action we use the three-dimensional high-temperature action including, besides temperature dependent masses, the TΦ one-loop contribution whcih makes the phase transition first order. The results show that this term...
متن کاملBubble Nucleation in Theories with Symmetry Breaking by Radiative Corrections
In any first order phase transition a quantity of fundamental importance is the rate at which bubbles of the equilibrium (“true vacuum”) phase nucleate within the metastable (“false vacuum”) phase. The bubble nucleation rate per unit volume, Γ, can be calculated by a method, due to Coleman, 1 which is based on finding a “bounce” solution to the classical Euclidean field equations. Thus, for a t...
متن کاملQuantum Corrections to Nucleation Rates
In this paper we show how to compute in a consistent way nucleation rates in field theory at finite temperatures, with metastable vacuum. Using the semiclassical approach in field theory at finite temperature we show that the prefactor term can be calculated explicitly (in the thin-wall approximation) and that the same provides exponential finite temperature quantum corrections to nucleation ra...
متن کاملOne-loop corrections to the bubble nucleation rate at finite temperature.
We present an evaluation of the 1-loop prefactor in the lifetime of a metastable state which decays at finite temperature by bubble nucleation. Such a state is considered in one-component φ-model in three space dimensions. The calculation serves as a prototype application of a fast numerical method for evaluating the functional determinants that appear in semiclassical approximations. e-mail ba...
