Non-linear coupling of quantum theory and classical gravity

Journal of Physics A: Mathematical and General, 1980
Discusses the possibility that the non-linear evolution proposed earlier for a relativistic quantum field theory may be related to its coupling to a classical gravitational field. Formally, in the Schrodinger picture, it is shown how both the Schrodinger equation and Einstein's equations (with the expectation value of the energy-momentum tensor on the ...

The timelessness of quantum gravity: I. The evidence from the classical theory

Classical and Quantum Gravity, 1994
The issue of time is addressed. It is argued that time as such does not exist but that instants, defined as complete relative configurations of the universe, do. It is shown how the classical mechanics (both non-relativistic and generally relativistic) of a complete universe can be expressed solely in terms of such relative configurations.
