摘要：

Using a lattice Langevin simulation we measure the decay rate of a metastable phase in (2 + 1)-dimensional classical scalar field theory coupled to a heat bath, which is equivalent to two-dimensional Euclidean quantum field theory at zero temperature. The nucleation barrier is found to be accurately predicted by the bounce configuration obtained from the tree-level (''classical'') effective action.
