Jordan-Brans-Dicke quantum wormholes and Coleman's mechanism
LJ Garay, J Garcia-Bellido - Nuclear Physics B, 1993 - Elsevier
We consider the quantum gravity and cosmology of a Jordan-Brans-Dicke theory, predicted
by string effective actions. We study its canonical formalism and find that the constraint …

On time and the quantum-to-classical transition in Jordan-Brans-Dicke quantum gravity
C Kiefer, EA Martinez - Classical and Quantum Gravity, 1993 - iopscience.iop.org
Any quantum theory of gravity which treats the gravitational constant as a dynamical variable
has to address the issue of superpositions of states corresponding to different eigenvalues …
