Report

This paper is motivated by the suggestion [W. Zurek, Physica Scripta, T76, 186 (1998)] that the chaotic tumbling of the satellite Hyperion would become non-classical within 20 years, but for the effects of environmental decoherence. The dynamics of q

Quantum-Classical Correspondence for the Equilibrium Distributions of Two Interacting Spins

Autor: Emerson, J., Ballentine, L. E.

Publikováno v: Phys. Rev. E 64, 026217 (2001).

We consider the quantum and classical Liouville dynamics of a non-integrable model of two coupled spins. Initially localised quantum states spread exponentially to the system dimension when the classical dynamics are chaotic. The long-time behaviour

Characteristics of Quantum-Classical Correspondence for Two Interacting Spins

Autor: Emerson, J., Ballentine, L. E.

Publikováno v: Phys. Rev. A 63, 052103 (2001); Erratum in PRA 64, 029901 (2001).

The conditions of quantum-classical correspondence for a system of two interacting spins are investigated. Differences between quantum expectation values and classical Liouville averages are examined for both regular and chaotic dynamics well beyond
