Stochastic inflation from quantum field theory and the parametric dependence of the effective noise amplitude
Abstract The non-linear dynamics of long-wavelength cosmological fluctuations may be phrased in terms of an effective classical, but Course a pied - Homme - Vetements - Manteau stochastic evolution equation.The stochastic noise represents short-wavelength modes that continually redshift into the long-wavelength domain.The effective evolution may be
