Cosmological Particle Production: A Review
  This article will review quantum particle creation in expanding universes.
The emphasis will be on the basic physical principles and on selected
applications to cosmological models. The needed formalism of quantum field
theory in curved spacetime will be summarized, and applied to the example of
scalar particle creation in a spatially flat universe. Estimates for the
creation rate will be given and applied to inflationary cosmology models.
Analog models which illustrate the same physical principles and may be
experimentally realizable are also discussed.
