Tunneling and Nucleation Rate in the (λϕ^4/4! + σϕ^6/6!)_3 Model

Abstract

We evaluate both the vacuum decay rate at zero temperature and the finite temperature nucleation rate for the $(\lambda {\varphi }^4/4!+\sigma {\varphi }^6/6!{)}_{3D}$ model. Using the thin-wall approximation, we obtain the bounce solution for the model and we were also able to give the approximate eigenvalue equations for the bounce.
