Any thoughts on the above? It is a pretty vague question. Sorry about that.

Note that this does not imply a quantization of the gravitational field. It is just a quantum particle in a classical, external, weak gravitational potential.

Particles are very helpful, they lend themselves to everything...

It depends on what you mean by "compatible with gravity." If you're asking if its valid if the Hamiltonian represents a gravitational field then yes. Otherwise I don't know what you're referring to.

I will have to refer to Mr Hawking in order to proceed.

That appears to be about quantum gravity, a field I'm not versed in. However I get the impression that the Hamiltonian in question is for the field and not for a particle. The Schrodinger equation in that case has nothing to do with it.

I'm still planning on reading the PDF though. I think I need Legendre transformations to get from a Lagrangian to a Hamiltonian.
