Decoherence: Basic Concepts and Their Interpretation

Abstract

Introduction to the theory of decoherence. Contents: 1. The phenomenon of decoherence: superpositions, superselection rules, decoherence by "measurements". 2. Observables as a derivable concept. 3. The measurement problem. 4. Density matrix, coarse graining, and "events". 5. Conclusions.

Draft for second edition of Chapter 2 of "Decoherence and the Appearance of a Classical World in Quantum Theory" (D. Giulini et al., Springer 2003). Further comments, references, and a new section "Conclusions" added. 42 pages, Latex (uses Springer macros), 3 eps-files
