“…With regards to Bell's theorem, such a background field would allow for Bell type correlations in simple local realistic ways. Such a de-localized background field trivially breaks the isolation assumption of the theorem according to [8]. This is not in violation of, but rather in accord with, Bell's theorem.…”

“…This is not in violation of, but rather in accord with, Bell's theorem. [9] considers [8] wrong claiming it implies a super-luminal communication in the background. We will now briefly review the literature for BIVs and show that there is little agreement as to what is causing the Bell correlations.…”

We report the experimental observations of Bell Inequality Violations (BIV) in entangled photons causally separated by a rotating mirror. A Foucault mirror gating geometry is used to causally isolate the entangled photon source and detectors. We report an observed BIV of CHSH-S = 2.30 ± 0.07 > 2.00. This result rules out theories that explain correlations with traveling communication between source and detectors.

In the quest for an understanding of nonlocality with respect to an appropriate ontology, we propose a "cosmological solution". We assume that from the beginning of the universe each point in space has been the location of a scalar field representing a zero-point vacuum energy that nonlocally vibrates at a vast range of different frequencies across the whole universe. A quantum, then, is a nonequilibrium steady state in the form of a "bouncer" coupled resonantly to one of those (particle type dependent) frequencies, in remote analogy to the bouncing oil drops on an oscillating oil bath as in Couder's experiments. A major difference to the latter analogy is given by the nonlocal nature of the vacuum oscillations.We show with the examples of double-and n-slit interference that the assumed nonlocality of the distribution functions alone suffices to derive the de˜Broglie--Bohm guiding equation for N particles with otherwise purely classical means. In our model, no influences from configuration space are required, as everything can be described in 3-space. Importantly, the setting up of an experimental arrangement limits and shapes the forward and osmotic contributions and is described as vacuum landscaping. * Corresponding author: ains@chello.at; http://www.nonlinearstudies.at arXiv:1806.05466v2 [quant-ph]

Are Hidden-Variable Theories for Pilot-Wave Systems Possible?

Recently it was shown that certain fluid-mechanical 'pilot-wave' systems can strikingly mimic a range of quantum properties, including single particle diffraction and interference, quantization of angular momentum etc. How far does this analogy go? The ultimate test of (apparent) quantumness of such systems is a Bell-test. Here the premises of the Bell inequality are re-investigated for particles accompanied by a pilot-wave, or more generally by a resonant 'background' field. We find that two of these premises, namely outcome independence and measurement independence, may not be generally valid when such a background is present. Under this assumption the Bell inequality is possibly (but not necessarily) violated. A class of hydrodynamic Bell experiments is proposed that could test this claim. Such a Bell test on fluid systems could provide a wealth of new insights on the different loopholes for Bell's theorem. Finally, it is shown that certain properties of background-based theories can be illustrated in Ising spinlattices. Introduction.Since the birth of quantum mechanics, physicists have been intrigued by its counterintuitive features, such as the collapse of the wave function, the uncertainty relations, wave-particle duality, the probabilistic nature of the theory, etc. Many attempts have been made to restore a more classic character to quantum mechanics, notably by efforts aiming at deriving the theory from a more fundamental, deeper-lying theorymaybe even a deterministic one. Such a hidden-variable theory (HVT) would contain yet unknown variables which, once integrated-out, yield quantum theory.This would after all be a familiar situation in physics: quantum mechanics would have the status of an 'effective' theory, as other theories. But this quest for sub-quantum theories, initiated by such giants as Einstein, de Broglie, Schrödinger etc., has been restrained, not only by the unprecedented precision and efficiency of quantum theory, but also by certain abstract mathematical results that seem to prove the impossibility of constructing any reasonable HVT. These are the so-called 'nogo' theorems, among which Bell's theorem [1-3] but also the Kochen-Specker theorem [4] are best known. What I call 'Bell's theorem' (as a physical, and not just mathematical, theorem) states, in short, that 'local hidden-variable theories are impossible'. It is essential here to be clear about what
