摘要

Particle creation in a conformally flat spacetime (e.g., FRW universe) requires a non-conformal field. The choice of state is crucial, as one may misunderstand the physics of particle creation by choosing a too restrictive vacuum for the quantum field. We exhibit a vacuum state in which the expectation values of the energy and pressure allow an intuitive physical interpretation. We apply this general result to the de Sitter universe.
