摘要
In many theories of reheating starting from the classical spatially
homogeneous inflaton field, its accompanying inhomogeneous part (which arises
from primordial quantum fluctuations) is treated as a first order perturbation.
We examine some consequences of treating it non-perturbatively in a model where
a first order treatment is invalid. In particular we consider effects on the
long-wavelength curvature parameter relevant to the cosmic microwave background
fluctuations.
