A procedure is outlined for the first-principles calculation of the rate of decay of a metastable phase. The mode1 on which the calculation is based is sufficiently genera1 to describe a wide variety of thermally activated nucleation and growth processes, hopefully even including decay of superflow
The relations between the stochastic and transition-state theories are reconsidered on the basis of a harmonic oscillator model. It is shown from the physical point of view that both theories are not equivalent.
Au extension of the usual system-size expansion method is given to study the relaxation and fluctuation from unstable and metastable states. The short-time and the long-time behavior of the moments y(t) and M,(t) and of the distribution function P(x, t) of a macrosco0ic variable x are investigated b
