J. Baacke et Vg. Kiselev, ONE-LOOP CORRECTIONS TO THE BUBBLE NUCLEATION RATE AT FINITE-TEMPERATURE, Physical review. D. Particles and fields, 48(12), 1993, pp. 5648-5654
We present an evaluation of the one-loop prefactor in the lifetime of
a metastable state which decays at finite temperature by bubble nuclea
tion. Such a state is considered in the one-component (phi(4) model in
three space dimensions. The calculation serves as a prototype applica
tion of a fast numerical method for evaluating the functional determin
ants that appear in semiclassical approximations.
