Decoherence and particle creation
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 f...

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 semiclassical evolution leads to particle creation. © 1990 The American Physical Society. |l eng | |
