The physical aspects of the wave-particle problem

Michael Danos, Vincent P. Gillet

This book is concerned with the practical aspects of solving angular momentum problems. The novel but fully tested-out method (the Invariant Graph Method) allows one to write down from a single graph the complete final result of the problem. The drawing of the graph involves very few simple, essentially self-evident rules. Still it is a powerful tool to easily solve the most involved physical problems. The method is introduced step-by-step in a sequence of examples, beginning with the simplest matrix elements, and ending with the most general case of a reaction including angular distributions and correlations. The many-body and particle anti-particle systems are fully developed. All aspects: wave functions, vectors, operators, Fock space state vectors and operators, etc., are treated on the same footing. All concepts of angular momentum theory acquire a transparent meaning. Hence the book is valuable not only as a handbook in problem solving, but extremely so as an adjunct in any course on advanced qunatum physics, atomic, molecular, nuclear and particle physics

Despite their author, de Broglie waves for ordinary (bradyonic) particles are often considered without physical signication, mainly because they are tachyonic. I revisit some of de Broglie’s original ideas and discuss the standard approach to the problem, the \wave packet overlapped to a de Broglie wave. Using Pseudotachyonic Theory, it’s easy to conclude that this tachyonic wave actually exists but may only be detected with the same velocity of its associated particle. Furthermore, in what comes to \dualities, it appears that wave and particle are not two aspects of the same thing but instead two different though intimately correlated entities. These reections concern the physical nature of de Broglie waves, including particles \internal vibration, and lead to the premises of a new general Field Theory. Including positive as well as negative

A particle is described as a non-spreading wave packet satisfying a linear equation within the framework of special relativity. Young's and other interference experiments are explained with a hypothesis that there is a coupling interaction between the peaked and non-peaked pieces of the wave packet. This explanation of the interference experiments provides a realistic interpretation of quantum mechanics. The interpretation implies that there is physical reality of particles and no wave function collapse. It also implies that neither classical mechanics nor current quantum mechanics is a complete theory for describing physical reality and the Bell inequalities are not the proper touchstones for reality and locality. The problems of the boundary between the macro-world and micro-world and the de-coherence in the transition region (meso-world) between the two are discussed. The present interpretation of quantum mechanics is consistent with the physical aspects of the Copenhagen interpretation, such as, the superposition principle, Heisenberg's uncertainty principle and Born's probability interpretation, but does not favor its philosophical aspects, such as, non-reality, non-objectivity, non-causality and the complementary principle.
