From classical chaos to decoherence in Robertson-Walker cosmology

We analyze the relationship between classical chaos and particle creation in Robertson-Walker cosmological models with gravity coupled with a scalar field. Within our class of models chaos and particle production are seen to arise in the same cases. Particle production is viewed as the seed of decoh...
