I wonder how Dirac equation transform under change of coordinates (in flat spacetime).
Should I simply express partial derivaties of one coordinates in another or it is
necessary to transform Dirac matrices as well?

There's a good review paper

Brill & Wheeler, Rev Mod Phys 29 (1957) 465

and many others subsequently, one off the top of my head is

Chamseddine, hep-th/0511074 (2005)


I'm a bit rusty on the details but I recall the Dirac matrices have to change so that the anticommutator relation
<br /> \gamma^\mu \gamma^\nu + \gamma^\nu \gamma^\mu = 2 g^{\mu\nu}<br />
remains true. There is some sort of spinor connection which is a spinor analog of the covariant derivative.

Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
