Phys. Rev. Lett. 81, 3571–3574 (1998)Chaos in Quantum CosmologyReceived 21 August 1997; published in the issue dated 26 October 1998 Most of the foundational work on quantum cosmology employs a simple minisuperspace model describing a Friedmann-Robertson-Walker universe containing a massive scalar field. We show that the classical limit of this model exhibits deterministic chaos and explore some of the consequences for the quantum theory. In particular, the breakdown of the WKB approximation calls into question many of the standard results in quantum cosmology. © 1998 The American Physical Society URL:
