| Abstract: | We consider a simple cosmological model in orderto show the importance of unstable particle creation forthe validity of the semiclassical approximation. Usingthe mathematical structure of rigged Hilbert spaces we show that particle creation is theseed of decoherence which enables the quantum toclassical transition. |
