Chaos and semiclassical limit in quantum cosmology

In this paper we present a Friedmann-Robertson-Walker cosmological model conformally coupled to a masive scalar field where the WKB approximation fails to reproduce the exact solution to the Wheeler-DeWitt equation for large universes. The breakdown of the WKB approximation follows the same pattern...
