- Abstract: Adopting a general framework for quantum-classical dynamics, we analyze the
interaction between quantum matter and a classical gravitational field. We
point out that, assuming conservation of momentum or energy, and assuming that
the dynamics obeys a particular decomposition property set out in the paper,
the classical gravitational field cannot change the momentum or energy of the
quantum system, whereas the quantum gravitational field can do so. Drawing upon
the fundamental relationship between conservation laws and the quantum
properties of objects, our analysis offers new perspectives for the study of
quantum gravity and provides a novel interpretation of existing experimental
observations, such as free fall.

First-class phase-space constraints may be relaxed if we interpret them as fixing the values of new degrees of freedom.
This idea goes back to Fock and Stueckelberg, leading to restrictions of the gauge symmetry of a theory.
In particular, in the case of canonical quantum gravity, the Fock--Stueckelberg approach is relevant to the so-called problem of time.

It can be shown that both concepts, when combined, result in inconsistencies, reinforcing the arguments for the necessity of a rigorous derivation of the nonrelativistic limit of gravitating quantum matter from first principles.
