Is Direct Brute Force Quantization Possible for Equations of Motion?

[lokofer]

"Brute force" quantization..

Let's suppose we have the "Equation of motions" for a particle:

$$F(y'',y',y,x)=0$$ my question is if exsit a "direct" method to apply quantization rules..for example simply stating that:

$$F(y'',y',y,x)| \psi (x) >=0$$ or something similar.

- I'm not talking about the usual method (you use the Hamiltonian operator to get the Wave function) but a method to "Quantize" everything without using Hamiltonians or Lagrangians only with the equation of motion and similar...thanks.

The Hellman-feynman theorem deals with the quantum mechanics of forces, but no, there is no procedure which involves quantised forces.

Well, I don't know about that theorem, but I was once thinking about quantum mechanics as a probability fluidum (the Madelung interpretation), something I never published since I cannot believe it has not been done yet. In this case, let $$R^2$$ be the ``mass´´ density and $$\partial_{\mu} S$$ be the integrable fluid velocity field. Then, the traditional navier stokes equation is:
$$R^2 \partial_t \partial_{\alpha}S + R^2 \partial_{\beta} S \partial_{\beta} \left( \partial_{\alpha} S \right) = \frac{R^2}{m} F_{\alpha} - \partial_{\alpha} p + \partial^{\beta} T_{\beta \alpha}$$ and the usual continuity equation
$$\partial_t R^2 + \partial^{\alpha} \left( R^2 \partial_{\alpha} S \right) = 0$$
Now, let the pressure $$p = - \frac{1}{2m^2} \left( R \partial_{\beta} \partial^{\beta }R - \frac{1}{3} \partial_{\beta} R \partial^{\beta} R \right)$$ and the stress tensor
$$T_{\alpha \beta} = - \frac{1}{m^2} \left( \partial_{\alpha}R \partial_{\beta} R - \frac{1}{3} \delta_{\alpha \beta} \partial_{\gamma} R \partial^{\gamma} R \right)$$ then it is easy to prove that
with $$F_{\alpha} = - \partial_{\alpha} V$$, the Navier Stokes equation gives rise to the Hamilton Jacobi equation of Bohmian mechanics. Hence, this provides a general scheme for quantization of particles in general force fields. If you definately know this has not been done yet, give me a sign and I will post the ``paper'' on the arxiv.

It seems to me you cannot quantize general force fields (in the case of instantaneous action at a distance, there are no traveling waves, hence no particles), only those which can be derived from a (eventually distributional) field theory seem to be meaningful.
