Hi all,
I've been looking at de Broglie-Bohm theory and more recent attempts at Bohm-like models that are relativistic and attempt to reproduce QFT. What I'm not clear on (non-expert) is how the vacuum is modeled in these cases? If we have a set of infinite quantum harmonic oscillators, wouldn't Bohm-like models have implications that there exist an infinite number of oscillators with exact positions at each point? (not getting into renormalization)
In particular, this paper https://arxiv.org/pdf/0903.0283.pdf (which has been published in New Adv. Phys. 3 (2009) 35-44) seems to suggest that (real Bohmian) particles are pushed around by vacuum fluctuations (@A. Neumaier may have something to say). The paper implies a statistical mechanics-type solution, ... but if this were true, wouldn't it be the case that you could extract energy from the vacuum?
Sorry if the above is not very clear - I'm having a hard time with the interpretation (of the interpretation...).
