Mechanism Interpretation of Double-Slit Interference Uncertainty and Measurement-Induced Interference Disappearance Based on Spatial Particle Resonance Propagation Model

Abstract

The double-slit interference experiment serves as a fundamental experiment in quantum mechanics. Core theories including wave-particle duality, quantum superposition and measurement collapse are established on the basis of this phenomenon. The mainstream Copenhagen interpretation and Bohmian pilot-wave theory rely heavily on mathematical statistical fitting to interpret experimental outcomes, yet they fail to reveal the real physical evolution mechanism of photons at the microscale. Moreover, they inherently suffer from symmetry breaking, causal discontinuity and logical inconsistency. The symmetry-breaking analogy widely adopted in academic circles contains dimensional mismatch and conceptual substitution, representing a cognitive bias that places mathematical tools above physical mechanisms. Based on the symmetry principle of classical physics and the rule of continuous causal evolution, this paper systematically identifies the core defects of mainstream quantum interpretations and points out the paradigm limitation of quantum mechanics that prioritizes mathematical fitting over physical ontology. A spatial particle resonance propagation model is proposed. This model explains that photons are essentially the resonance manifestation of space particles. When resonance passes through double slits, the resonance body splits symmetrically, and then recombines after passing through the slits to form interference. Measurement will break the symmetry of resonance, resulting in the disappearance of interference fringes. This model maintains continuous causality and geometric symmetry, and provides a new physical mechanism explanation for quantum uncertainty and measurement effects in double-slit experiments.

The Double-Slit Experiment Reinterpreted: Matter-Wave Propagation and the Physical Mechanism of Quantum Interference

YOUNG HO GOH

The double-slit experiment has stood for a century as the paradigmatic demonstration of quantum superposition: the standard interpretation holds that a particle passes through both slits simultaneously, existing in a superposition of two spatially separated states. This paper proposes a physically distinct alternative: the particle's matter wave — a real physical wave propagating through space in accordance with de Broglie's relation λ = h/p — passes through both slits, while the particle itself (matter) remains in an undetermined state until a constructive interference maximum is formed at the detection screen. The particle does not simultaneously occupy two locations; the wave does. This distinction eliminates the need for superposition as an ontological commitment while fully reproducing the observed interference pattern. We further show that the disappearance of the interference pattern upon which-path measurement is explained without invoking wavefunction collapse: the measurement interaction redirects the matter wave to a single-slit geometry, eliminating the two-wave interference condition. Three experimentally testable predictions distinguish this framework from the standard interpretation: (1) weak-measurement trajectory reconstruction should reveal single particle paths inconsistent with simultaneous two-slit passage; (2) diffraction fringe spacing should depend on the mass density of the slit material, because denser slit edges generate a steeper refractive-index gradient for the matter wave; (3) the fringe pattern should exhibit a density-dependent phase shift measurable with current matter-wave interferometry technology. This reinterpretation requires no new mathematical formalism — the Schrödinger equation and Born's rule are retained — but replaces the ontological claim of simultaneous multi-location existence with the physically consistent picture of matter-wave propagation through an undetermined-state particle.

DOUBLE SLIT EXPERIMENT AND WAVE-PARTICLE DUALITY

V. Abbasov

Abstract The double-slit experiment is a classic experiment that presents the clearest manifestation of wave-particle duality, one of the fundamental principles of quantum mechanics. The double-slit experiment still remains the phenomenon that demonstrates wave-particle duality at the most fundamental level. This phenomenon quantitatively and conceptually demonstrates that microscopic objects can behave like both waves and particles at the same time. This article provides an in-depth analysis of the physical nature of dualism, the mechanism of formation of the interference pattern, and the impact of the act of observation on the dynamics of quantum systems. The need for a new perspective on this topic is due to the fact that the current uncertainty in the interpretation of quantum reality has not yet been completely eliminated, and the boundaries between classical and quantum behavior in microscopic objects are still being explored. The results presented here restructure the deep mechanisms of the interference picture, more clearly frame the relationship between observation and wavefunction collapse, and provide a quantum. Since the article attempts to provide a complete answer to the mechanism of the formation of wave-particle duality, extensive space is given to sections such as historical development, theoretical models, modern research, etc. New approaches to this phenomenon have been developed using modern research and string theory. As a result, a new mathematical expression has been proposed that explains the reasons for the initial emergence of wave-particle duality, and is also important for string theory. The article explains the measurement problem with a more effective physical structure and ontological model.

The Illusion of Quantum Mechanics: A Critique and Reflection on the Mainstream Interpretation of the Double-Slit Experiment

Jiqing Zeng

The double-slit experiment, as a cornerstone experiment of quantum mechanics, has long been regarded as the ultimate proof of wave-particle duality. However, results from high-precision experiments conducted in recent years by teams including Tonomura and Bach, as well as from the "recoiling slit" experiment by Jianwei Pan's team, have revealed profound contradictions with mainstream quantum mechanical interpretations. These contradictions expose systematic biases in conceptual definitions and the interpretation of physical mechanisms within the mainstream narrative. Based on particle flow scattering theory and incorporating the design details and results of Pan's team's experiment, this paper critiques the mainstream quantum mechanical narrative that mystifies the "cumulative effect of particle flow scattering" as "wave-particle duality" and "wave function collapse." It argues that the essence of the bright and dark fringes in the double-slit experiment is the statistical distribution of particles after their interaction with slit matter, rather than wave interference. Research indicates that the core dilemma of mainstream quantum mechanical interpretation stems from a misreading of the physical essence of experiments and conceptual confusion. Reconstructing a physical picture based on classical scattering theory and statistical laws is the inevitable path for quantum mechanics to overcome its interpretational predicament.

Interpretation of quantum mechanics

Benjamín de Zayas

The standard Copenhagen interpretation of quantum mechanics relies on a set of historically established, ad hoc postulates to describe particle-wave duality, measurement, and non-locality. In this paper, we propose a single foundational axiom that fully reproduces the standard mathematical formalism of quantum mechanics while eliminating the need for supplementary assumptions. From this singular postulate, we rigorously derive the fundamental origin of the wave function and the mathematical generator of the Schrödinger equation. Furthermore, we demonstrate via isomorfism that all seemingly inexplicable quantum phenomena—including wave-function collapse and quantum entanglement—are mathematically and conceptually reducible to the underlying dynamics of the double-slit experiment. By establishing a direct fundamental correlation between the double-slit interference mechanism and the Monty Hall phenomenon, we prove that these effects are distinct manifestations of the exact same principle. We framed the double-slit experiment as an interference of the space of possibilities affected by information and simetrys. Ultimately, by anchoring the existing quantum mathematical framework to this unique axiom, this work provides a coherent, paradox-free ontological foundation that resolves the interpretational crisis of quantum mechanics without altering its empirical predictive power.

A Unified Physical Mechanism of Electron Single-Slit and Double-Slit Diffraction Based on Electromagnetic Interaction and Particle Exchange at Slit Walls

Jiaqing Yan

The mainstream quantum mechanics uses “probability wave superposition and single-electron self-interference” to explain electron single-slit and double-slit diffraction. This theory deviates from the essential nature of real particle interactions and has fundamental logical flaws. The electron is a negatively charged real particle with a definite physical size and high-frequency transverse oscillation; a single real particle has no physical basis for self-interference. Abandoning the abstract probability wave hypothesis, this paper establishes a complete real-interaction model including electrostatic repulsion deflection, surface electron exchange, collision scattering, microscopic refraction, and barrier diffraction, based on the three-dimensional random transverse oscillation and charge repulsion of electrons. The model uniformly explains the real formation mechanism of electron single-slit diffraction and double-slit interference fringes. This paper proves that in single-electron sequential emission, each electron passes through only one slit; all bright and dark fringes are the statistical result of multiple microscopic interactions between electrons and slit walls or the central barrier. The disappearance of fringes under observation is caused by external disturbance to the inherent oscillation and wall-interaction equilibrium, not by wave function collapse. This paper further clarifies that whether an electron can pass through a slit is determined by its transverse oscillation amplitude, not by wavelength. Amplitude directly corresponds to slit width and is the core controlling variable of diffraction. Meanwhile, if no slit is placed, electrons flying directly to the screen produce no diffraction or interference fringes, proving that electrons themselves have no self-interference ability. Fringes are generated by slit structures, not by intrinsic wave interference of electrons. This study corrects the century-long misunderstanding of electron diffraction and establishes a new microscopic diffraction mechanism consistent with classical real-particle physics.

A New Interpretation of the Recoiling-Slit Quantum Interference Experiment

Jiaqing Yan

In December 2025, Pan Jianwei’s research team reproduced the Einstein-Bohr recoiling-slit thought experiment proposed in 1927 at the quantum limit. They observed that the interference fringe contrast changes continuously with the momentum of the slit. Mainstream physical theories currently regard this phenomenon as critical evidence for the quantum complementarity principle. Based on the Light Primitive Theory, this paper points out that all relevant theoretical models established since the century-long debate at the Solvay Conference contain two fundamental idealized simplifications: first, physical slits are abstracted as two-dimensional geometric holes with zero thickness; second, the inherent continuous spatial oscillation of photons is ignored. Photons are not point-like particles moving along fixed straight lines. Their persistent oscillation enables continuous momentum coupling between photons and the photon self-locked matter forming the slit walls throughout the whole passage through the physically thick slit channel. The inverse correlation between path detectability and interference fringe visibility observed in the experiment can be self-consistently explained by continuous photon-slit wall interaction, without abstract hypotheses such as wave-particle complementarity or quantum superposition. This paper supplements the objective physical conditions missing from traditional models and provides a brand-new interpretative framework for quantum interference phenomena at the underlying mechanism level.
