Prediction in Quantum Cosmology
James B. Hartle (University of California, Santa Barbara)
TL;DR
This paper discusses quantum cosmology, focusing on the Wheeler-DeWitt equation, the classical limit, and quantum field theory in curved spacetime, based on lectures from 1986 with some updated perspectives.
Contribution
It provides insights into the Born-Oppenheimer approximation and classical geometry limit in quantum cosmology, reflecting the author's views and historical context.
Findings
Analysis of the Wheeler-DeWitt equation solutions
Discussion on the classical geometry limit
Application of quantum field theory in curved spacetime
Abstract
Lectures by the author at the 1986 Cargese summer school modestly corrected and uploaded for greater accessibility. Some of the author's views on the quantum mechanics of cosmology have changed from those presented here but may still be of historical interest. The material on the Born-Oppenheimer approximation for solving the Wheeler-DeWitt equation and the work on the classical geometry limit and the approximation of quantum field theory in curved spacetime are still of interest and of use.
