    "abstract": "Bohm Mechanics and Nelson Stochastic Mechanics are confronted with Quantum\nMechanics in presence of non-interacting subsystems. In both cases, it is shown\nthat correlations at different times of compatible position observables on\nstationary states agree with Quantum Mechanics only in the case of product wave\nfunctions. By appropriate Bell-like inequalities it is shown that no classical\ntheory, in particular no stochastic process, can reproduce the quantum\nmechanical correlations of position variables of non interacting systems at\ndifferent times.",
