comment Interpretation of the Random Schrödinger Equation
@RonMaimon:Thx for your reference, I already studied the original paper from Parisi and Sourlas, and reviewed the supersymmetric approach to stochastic problems on Zinn-Justin's book, and some Gozzi's papers. I'll take a look at Oz's article :)

@Qmechanic : can you suggest me some reference about the trace regularization?

Great insight :) Thanks

comment Interpretation of the Random Schrödinger Equation
@Ron Maimon : Actually this is a very interesting answer. Could you provide me some references about the supersymmetric approach to obtain mean quantities? I am currently studying a random electromagnetic system, and after attacking it with the replica-trick, I'm willing to try the more rigorous SUSY formulation, but I cannot find more detalied information on it.

answered What is replica symmetry breaking, and what is a good resource for learning it?

comment Gaussian Integrals : Functional determinant expressed as a trace
@Vibert : Actualy expanding the $\log$ was my idea. Provided idk how to manage an expansion over "abstract operators", I would like to project the whole $\mathrm{Tr} \log [..]$ over $x$ or $k$, and then expand the projected logarithm. But how exactly does a $\mathrm{Tr}$ projection work?

comment Gaussian Integrals : Functional determinant expressed as a trace
Symmetric matrix, sorry, I wrote it wrong. In the full calculation I have to do, $\varphi$ is a real field and $\psi$ is a grassman-odd variable.
