摘要：

We demonstrate the relationship between the loss of coherence between contracting and expanding histories in the wave function of the Universe and particle creation from the gravitational field. In a minisuperspace model describing a spatially closed Robertson-Walker universe plus a quantum scalar field, the wave function of the Universe will decohere if and only if the corresponding semi-classical evolution leads to particle creation.
