Experimental Evidence on the Real Physical Existence of the Subquantum Waves

Abstract

The question related with the ontic nature of the quantum waves, whether they are mere probability waves or, on the contrary, do have a real physical existence is now settled by recent experiments based on ghost imaging technique. Indeed, these experiments have shown the real physical existence of subquantum waves, named also de Broglie waves, guiding waves, pilot waves, theta waves or subquantum waves. In order to better clarify the situation some minor modifications on the performed experiments are proposed.

Guiding Waves in Quantum Mechanics

Abstract The pilot-wave theory of de Broglie and Bohm has a special place in the history of contemporary physics, being it the very first alternative formulation of quantum mechanics. As is well-known, such a framework established itself as a leading interpretation of the quantum formalism in virtue of the solutions provided to the major technical and conceptual challenges affecting the orthodox view. The de Broglie-Bohm theory in fact not only solves the famous measurement problem, one of the most cogent issues faced by standard quantum mechanics, but also it clarifies the formal structure of the latter theory as a consequence of a consistent set of principles and an precise, unambiguous ontology. This volume aims to provide the reader with a discussion of the pilot-wave perspective which is as informative, comprehensive and accessible as possible, while at the same time clarifying confusions and misunderstandings that are unfortunately still common in literature despite the long history of this theoretical framework. The book features chapters about the various perspectives on the pilot-wave theory, its extensions to relativity and quantum field theory, and its experimental applications to various branches of physics, as for instance quantum electrodynamics, quantum chemistry, and quantum engineering. Moreover, the volume includes essays on the history and philosophy of de Broglie-Bohm theory in order to delineate its developments and the vicissitudes of its pioneers, as well as to understand the scientific image of the universe it provides.

Louis de Broglie Realistic Research Program and the experimental detection of Quantum Waves

J. R. Croca, P. G. Castro, Marisa Della Gatta +1 more

We give a brief historical review of Louis de Broglie realistic research program as developed in Lisbon’s research group about nonlinear quantum physics. We propose and discuss “yes-no” type experiments to physically detect quantum waves, independently of the associated corpuscles. Thus, deciding if they are real physical perturbations or mere probability waves. We finally present a possible technological application for the detection of such waves in quantum communication.

De Broglie-Bohm Pilot-Wave Theory: Many Worlds in Denial?

Antony Valentini

We reply to claims (by Deutsch, Zeh, Brown and Wallace) that the pilot-wave theory of de Broglie and Bohm is really a many-worlds theory with a superfluous configuration appended to one of the worlds. Assuming that pilot-wave theory does contain an ontological pilot wave (a complex-valued field in configuration space), we show that such claims arise from not interpreting pilot-wave theory on its own terms. Specifically, the theory has its own ('subquantum') theory of measurement, and in general describes a 'nonequilibrium' state that violates the Born rule. Furthermore, in realistic models of the classical limit, one does not obtain localised pieces of an ontological pilot wave following alternative macroscopic trajectories: from a de Broglie-Bohm viewpoint, alternative trajectories are merely mathematical and not ontological. Thus, from the perspective of pilot-wave theory itself, many worlds are an illusion. It is further argued that, even leaving pilot-wave theory aside, the theory of many worlds is rooted in the intrinsically unlikely assumption that quantum measurements should be modelled on classical measurements, and is therefore unlikely to be true.

De Broglie’s relativistic phase waves and wave groups

Harvey R. Brown, Roberto de Andrade Martins

Louis de Broglie’s original theory of matter waves has until very recently received relatively little treatment in the literature on history and foundations of physics. This paper attempts to clarify a number of aspects of de Broglie’s theory, as formulated primarily in his famous thesis, which still give rise to confusion or debate. To this end, a re-examination is made of the scope and validity of the relativistic physics employed in de Broglie’s arguments concerning the existence of phase waves and their physical implications. Recent doubts concerning the soundness of de Broglie’s introduction of a wave group associated with the quantum are also analyzed in detail, and it is argued that the wave group indeed has a problematic, if minor, role in the overall theory.

Experimental Evidence for Physical Reality of Theta Wave by Change in Radionuclide Decay Rates

Paulo Maurício

By analysis performed on two independent experiments on radionuclide decay rates, we inferred the physical reality of de Broglie waves. The unexpected result of a variation of decay rates of 32Si and 226Ra with Earth-Sun inverse squared distance, clearly related with solar neutrino flux, is accounted here as a physical action of de Broglie empty waves. The highly illusive neutrino could not account for that rate change unless we consider them as a quantum particle in the causal and non-linear quantum physics framework. Other experiment here studied relating solar flares and changes in 54Mn decay rate reinforce the assumption that the solar neutrino flux is the reason for that variation, with neutrino as a quantum particle in de Broglie framework. In addiction, over and above of discuss further possibilities to confirm, or not, ours conclusions, we report some experimental setups which is

Experimental test of the de Broglie guided-wave theory for photons

L. J. Wang, X. Y. Zou, L. Mandeļ

A two-photon interference experiment has been carried out, based on an idea recently proposed by Croca, Garuccio, Lepore, and Moreira. The experiment is designed to test a prediction of the de Broglie guided-wave theory, according to which the waves have a physical reality in addition to yielding photon detection probabilities. The results clearly contradict the de Broglie theory, but are consistent with conventional quantum mechanics.
