The Problem of Classical Limit in Quantum Cosmology: The effective action language

General Relativity and Quantum Cosmology 2009-10-28 v1

Abstract

The tool of functional averaging over some ``large'' diffeomorphisms is used to describe quantum systems with constraints, in particular quantum cosmology, in the language of quantum Effective Action. Simple toy models demonstrate a supposedly general phenomenon: the presence of a constraint results in ``quantum repel'' from the classical mass shell.
