The weak field limit of quantum matter back-reacting on classical spacetime
Isaac Layton, Jonathan Oppenheim, Andrea Russo +1
Consistent coupling of quantum and classical degrees of freedom exists so long as there is both diffusion of the classical degrees of freedom and decoherence of the quantum system.…

Covariant path integrals for quantum fields back-reacting on classical space-time
Jonathan Oppenheim, Zachary Weller-Davies
We introduce configuration space path integrals for quantum fields interacting with classical fields. We show that this can be done consistently by proving that the dynamics are co…
