Resumen:
We study the process of vacuum decay in quantum field theory focusing
on the stochastic aspects of the interaction between long- and
short-wavelength modes. This interaction results in a diffusive behavior
of the reduced Wigner function describing the state of long-wavelength
modes, and thereby to a finite activation rate even at zero temperature.
This effect can make a substantial contribution to the total decay
rate.
