Stochastic model for the motion of correlated photon pairs
No full textIf one analyzes the stochastic behaviour of two massive (mγ≠0) photons imbedded in Dirac's vacuum one obtains (with stochastic jumps at velocity of light) the two-particle Proca equations which one can use to interpret (i) the first results of the Aspect experiment; (ii) the future issues of the complete Aspect and Rapisarda experiments, if they will violate Bell's inequality
SINGLE-PARTICLE TRAJECTORIES AND INTERFERENCES IN QUANTUM-MECHANICS
No full textIn this paper some topics concerning the possibility of describing phenomena of quantum interference in terms of individual particle spacetime trajectories are reviewed. We focus our attention, on the one hand, on the recent experimental advances in neutron and photon interferometry and, on the other hand, on a theoretical analysis of the description of these experiments allowed by stochastic mechanics. It is argued that, even if no conclusive argument is yet at hand in both the theoretical and the experimental fields, the researches of the last 10 years now seem to favor Einstein's and de Broglie's realistic spacetime description and interpretation of quantum mechanics. © 1992 Plenum Publishing Corporation
Stochastic derivation of the Dirac equation in terms of a fluid of spinning tops endowed with random fluctuations at the velocity of light
No full textStochastic derivation of Proca's equation in terms of a fluid of Weyssenhoff tops endowed with random fluctuations at the velocity of light
No full textOn two conflicting physical interpretations of the breaking of restricted relativistic Einsteinian causality by quantum mechanics
No full textAn attempt is made to discuss contradictory aspects of two conflicting interpretations that have been proposed concerning the possible experimental confirmation of quantum-mechanical predictions about a problem referred to as the 'EPR paradox'. The first interpretation apparently states that no information or energy travels faster than light and treats spacelike vectors as a combination of two timelike vectors representing a sum of retarded and advanced potentials; the second is reportedly an extension of a model of the causal interpretation of quantum mechanics in terms of a fluid with irregular stochastic fluctuations. Several relevant analyses are carried out
Causal superluminal interpretation of the Einstein-Podolsky-Rosen paradox
No full textA quantitative description of a model involving a causal superluminal interpretation of the Einstein-Podolsky-Rosen (EPR) paradox is presented for the simple case of two identical correlated scalar particles. The first form of the EPR paradox (i.e., simultaneous measurement of positions and momenta) discussed in the framework of the causal interpretation by Bohm and Hiley (1975) is interpreted in this context. The evident connection between this viewpoint and the superluminal tachyon interactions introduced by Bilaniuk et al. (1962) is analyzed. It is shown that superluminal phaselike photonlike collective motions of the quantum potential in Dirac's 'ether' do not induce the paradoxes of tachyon theory
2ND-ORDER WAVE-EQUATION FOR SPIN-1/2 FIELDS - 8-SPINORS AND CANONICAL FORMULATION
No full textThe algebraic structure of the 8-spinor formalism is discussed, and the general form of the 8-component wave equation, equivalent to the second-order 4-component one, is presented. This allows a canonical formulation that will be the first stage of the future Clebsch parametrization, i.e., a relativistic generalization of the Bohm-Schiller-Tiomno pioneering work on the Pauli equation. © 1988 Plenum Publishing Corporation
