Bohm Trajectories as Approximations to Properly Fluctuating Quantum Trajectories
arXiv:1308.5021
Abstract
We explain the approximate nature of particle trajectories in Bohm's quantum mechanics. They are streamlines of a superfluid in Madelung's reformulation of the Schrödinger wave function, around which the proper particle trajectories perform their quantum mechanical fluctuations to ensure Heisenberg's uncertainty relation between position and momentum.
