The shadow of light: further experimental evidences

We report the results of a double-slit-like experiment in the infrared range, which confirm those of a previous one by evidencing an anomalous behaviour of photon systems under particular (energy and space) constraints. These outcomes (independently confirmed by crossing photon beam experiments in both the optical and the microwave range) apparently rule out the Copenhagen interpretation of the quantum wave, i.e. the probability wave, by admitting an interpretation in terms of the Einstein-de Broglie-Bohm hollow wave for photons. Moreover, this second experiment further supports the interpretation of the hollow wave as a deformation of the Minkowski space-time geometry

New experimental results on the lower limits of local Lorentz invariance

An experiment aimed at detecting a DC voltage across a conductor induced by the steady magnetic field of a coil, carried out in 1998, provided a positive (although preliminary) evidence for such an effect, which might be interpreted as a breakdown of local Lorentz invariance. We repeated in 1999 the same experiment with a different experimental apparatus and a sensitivity improved by two orders of magnitude. The results obtained are discussed here in detail. They confirm the findings of the previous experiment, and show, among the others, that the effect is independent of the direction of the current. A possible interpretation of the results is given in terms of a geometric description of the gravitational and the electromagnetic interactions by means of phenomenological, energy-dependent metrics

“The shadow of light: non-Lorentzian behavior of photon systems"

We discuss the theoretical foundations and the results of a double slit diffraction-like experiment in the infrared range, aimed at finding departures from the classical predictions. We found indeed an anomalous behavior of such a photon system. Possible interpretations can be given in terms of either the existence of de Broglie-Bohm hollow waves associated to photons, and/or a breakdown of local Lorentz invariance (LLI). The findings of the present experiment do agree with the threshold behavior in energy and space, recently derived (on an experimental basis) for the LLI breaking effect. This leads us to put forward the intriguing hypothesis that the hollow wave is a deformation of the space-time (Minkowskian) geometry. Our experimental findings have been tested in crossed photon-beam experiments, whose preliminary results evidence an anomalous behavior in the photon-photon cross section and confirm the threshold behavior in energy and space of the effect we observed.

The shadow of light: Lorentz invariance and complementarity principle in anomalous photon behavior

We review the results of two double-slit-like experiments in the infrared range, which evidence an anomalous behavior of photon systems under particular (energy and space) constraints. These outcomes (independently confirmed by crossing photon beam experiments in both the optical and the microwave range) apparently rule out the Copenhagen interpretation of the quantum wave, i.e. the probability wave, by admitting an interpretation in terms of the Einstein-de Broglie-Bohm hollow wave for photons. Moreover, these experiments support the interpretation of the hollow wave as a deformation of the Minkowski space-time geometry. We stress the implications of these experimental results and of their interpretation for the concept of action-at-a distance, Einstein's relativistic correlation and Bohr's principle of complementarity
