Wave optics, including diffraction, seems to be apt for path integral language. In fact, Feynman's double slit language is purely "diffraction". Also, the PDE for the wave equation results in a solution via Green's function, and the Green function is where "the path integral lives".
I have googled and there are a few references with somewhat blurry claims. I have not seen a explicit derivation.
Does anybody know if this program is possible, and if so, where is it derived?
