martinbn said:Yes, the pilot wave would be an example, but my puzzlement remains. How can something have and external existence and its mathematical discription be a function defined on configuration space?! I think that is what bohm2 is saying also.
The same way the Bohm pilot wave, which can also be viewed the same way can:
http://www-physique.u-strasbg.fr/cours/l3/divers/meca_q_hervieux/Articles/Nine_form.pdf
'The quantum potential Q(x1,x2,t) changes instantaneously throughout configuration space whenever the wavefunction changes, and this mechanism is responsible for the nonlocal correlations that are so characteristic of quantum mechanics. A rather natural mechanism prevents human beings from tapping into this instantaneous change for the purpose of faster-than-light communications.'
Interestingly that paper discusses another equivalent formulation of Quantum mechanics, the Second Quantization Formulation, usually associated with QFT, but can also be a formulation for bog standard QM, which can be viewed as a field of creation and annihilation operators at all points of space.
