摘要：
A method for determining the leading quantum contributions to the effective action for both zero and finite temperatures is presented. While it is described in the context of a scalar field theory, it can be straightforwardly extended to include fermions. An extrapolation procedure which can significantly enhance the computational efficiency is introduced. This formalism is used to investigate quantum corrections to the nucleation rate in first-order phase transitions.
