While the de Broglie wavelength pops up in various fundamental quantun-mechanical equations, a solid geometric interpretation of it has so far evaded us. This paper (part of an upcoming) book may help to crack the nut.
The physical origin of the de Broglie wavelength remains one of the central interpretive questions in quantum mechanics. This work is developed within the Zero-field framework, a phenomenological model in which space is treated as a continuous medium containing localized regions of inward energy flow toward particle-centered Zero-fields. Within this framework, moving particles generate rotation-induced guiding structures referred to as Frontal Waves. These waves are proposed to accompany particle motion and provide a geometric interpretation of the de Broglie wavelength and wave–particle duality. The proposed Frontal Wave wavelength reproduces the standard de Broglie relation and is interpreted as the physical guiding structure associated with matter-wave behavior. The framework is applied to the Double Slit Experiment and the Mach–Zehnder interferometer, where Frontal Waves propagate through multiple paths and form interference structures that guide particle trajectories toward regions of constructive interference. Connections with Bohmian mechanics are discussed, emphasizing that the model serves as a phenomenological interpretation rather than a modification of the mathematical formalism of quantum mechanics. The Frontal Wave concept provides a geometric picture of matter-wave behavior and offers a unified interpretation of particle guidance, interference phenomena, and the de Broglie wavelength within the broader Zero-field framework.
In this article, it is shown that if a particle is at rest and has some harmonic oscillation, then a traveling particle with a constant speed corresponds to a De Broglie Wave.In 1924, De Broglie proposed that particles of matter exhibit wave like behavior, the expression for which became fundamental in the creation of wave mechanics (quantum mechanics).The main equation for this is the Schrödinger equation, which in the case of free motion of a particle becomes the expression for the De Broglie wave.This hypothesis is supported by many early experiments on the diffraction of electrons, and later the development of modern physics.However until now, the origin of this hypothesis remains unclear.We show that the expression for the De Broglie wavelength can be obtained from a more general well-known concept, that any particle at rest has a corresponding harmonic oscillation that transforms into a wave of a moving particle with the help of relativistic change of coordinates (the Lorentz transformations).In this way, a De Broglie wave can be explained as a spacetime wave.
