Classicality, the Ensemble Interpretation, and Decoherence: Resolving the Hyperion Dispute

Decoherence and the (non)emergence of classicality

We prove that, regardless of the Hamiltonian, decoherence of subsystems in a preferred “pointer” basis does not occur for generic quantum states. This shows that the widespread belief that decoherence explains the emergence of classicality is incorrect, and that the emergence of classicality is only to be expected for a very small set of states.

The Emergence of Classicality via Decoherence Described by Lindblad Operators

Zurek, Habib and Paz [W. H. Zurek, S. Habib and J. P. Paz, Phys. Rev. Lett. 70 (1993) 1187] have characterized the set of states of maximal stability defined as the set of states having minimum entropy increase due to interaction with an environment, and shown that coherent states are maximal for the particular environment model examined. To generalize these results, I consider entropy producti...

Preferred Observables, Predictability, Classicality, and the Environment-induced Decoherence

Selection of the preferred classical set of states in the process of decoherence – so important for cosmological considerations – is discussed with an emphasis on the role of information loss and entropy. Persistence of correlations between the observables of two systems (for instance, a record and a state of a system evolved from the initial conditions described by that record) in the presence...
