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 problem of wave-particle duality is considered within the framework of the algebraic approach. Contrary to the widespread belief, we demonstrate that wave-particle duality can be reconciled with the assumption that there exists some local physical reality determining the results of local measurements. A number of quantum experiments—double-slit electron scattering, Wheeler’s delayed choice experiment, the past of photons passed through the interferometer—are discussed using the concept of locality. A clear physical interpretation of these experiments that does not contradict classical concepts is provided.
The delayed-choice experiment has long been regarded as one of the most conceptually intriguing demonstrations in quantum mechanics because the measurement configuration can be selected after a quantum system has already entered the experimental apparatus. This feature has often been interpreted as suggesting that the present measurement determines whether the quantum system behaved as a wave or as a particle in the past, thereby motivating discussions of wave–particle duality and retrocausality. This paper reexamines the delayed-choice experiment from the perspective of the Intrinsic Observability Framework (IOF). Rather than interpreting the experiment as demonstrating that the past is modified or that a quantum system intrinsically possesses either wave-like or particle-like properties prior to measurement, the IOF distinguishes between the pre-measurement domain of Potential Observability (PO) and the operational establishment of Observability through measurement. Within this framework, wave-like and particle-like behaviors are interpreted as observable representations established under different accessibility bases rather than intrinsic properties of the quantum system itself. Measurement grants accessibility, thereby establishing an observable representation according to the selected accessibility basis, within which observable values become operationally defined. Consequently, the delayed choice is understood not as selecting whether the quantum system was previously a wave or a particle, but as selecting the accessibility basis through which observability is established. From this perspective, the traditional wave–particle duality is reinterpreted as the basis dependence of observable representation rather than the coexistence of two fundamentally different physical natures. The delayed-choice experiment therefore illustrates how different accessibility bases lead to different observable representations while remaining fully compatible with the standard mathematical formalism of quantum mechanics.
The wave-particle duality mystery, present in the language of quantum physics since its historical origins 100 years ago, has no real correspondence with the actual behaviour of nature when it is observed. The dilemma of the so-called “single particle interference” experiments is not between particles versus waves: the interference in quantum physics is between probability amplitudes for different untagged alternatives in a definite transition between states. This article shows that the same conceptual basis is involved in a plethora of “two-state systems” as a consequence of the linear superposition principle, no matter whether the observables refer to either spatial or internal properties. Several examples, from the Young double-slit interference experiments to neutrino flavour oscillation experiments, are discussed in a common interpretation language.
The basic premise of Quantum Mechanics, embodied in the doctrine of wave-particle duality, assigns both, a particle and a wave structure to the physical entities. The classical laws describing the motion of a particle and the evolution of a wave are assumed to be correct. Gauge Mechanics treats the discrete entities as particles, and their motion is described by an extension of the corresponding classical laws. Quantum mechanical interpretations of various observations and their implications, including some issues that are usually ignored, are presented and compared here with the gauge mechanical descriptions. The considerations are confined mainly to the conceptual foundations and the internal consistency of these theories. Although no major differences between their predictions have yet been noticed, some deviations are expected, which are indicated. These cases may provide the testing grounds for further investigations.
The Observer Effect and Wave–Particle Duality in the S-field Framework --- 1. The traditional wave–particle problem In standard quantum mechanics, physical entities appear to behave: • as waves in interference experiments; • as particles when measured or detected. This has led to the idea that observation itself changes reality, often formulated as: “measurement collapses the wavefunction”. However, this formulation leaves unresolved questions: • What qualifies as an observer? • Why should information acquisition alter physical law? • Where exactly does the transition occur? --- 2. S-field perspective: no wave, no particle as primitives In the S-field framework, neither “wave” nor “particle” is fundamental. At the base level, there exist only: • oscillatory S-field states; • phase, frequency, and orientation; • dynamic resonance patterns. Wave and particle are emergent regimes, not ontological categories. 3. Wave behavior: coherent phase evolution A system exhibits wave-like behavior when: • S-oscillations evolve coherently; • multiple phase paths remain phase-correlated; • no dominant resonance locking occurs. In this regime: • interference patterns arise naturally; • delocalization reflects phase superposition; • the system evolves as a distributed resonance structure. “Wave” behavior is therefore a manifestation of extended phase coherence. --- 4. Particle behavior: resonance locking Particle-like behavior emerges when: • the S-oscillatory ensemble undergoes strong phase locking; • coherence collapses into a dominant resonant configuration; • the system enters a stable 4D projection. Localization is not imposed externally — it is a self-organized resonance outcome. A “particle” is a stable, self-locked oscillatory ensemble. 5. What observation actually does Observation does not create reality and does not collapse a wavefunction. Instead, observation means: • physical interaction with an environment; • introduction of new S-field couplings; • modification of phase relations. This interaction typically: • reduces global phase coherence; • enforces resonance selection; • stabilizes a particular outcome. Thus, observation is not epistemic — it is dynamical. --- 6. Why which-path information destroys interference Interference disappears because: • phase correlations are disrupted; • alternative phase paths decohere; • the system is forced into locally stable resonance modes. Which-path information is not special — any interaction that breaks coherence removes interference. No observer consciousness is required. 7. Delayed-choice experiments In delayed-choice scenarios: • the system remains in a coherent oscillatory regime; • no definitive resonance locking occurs until interaction; • temporal ordering appears paradoxical only classically. In the S-field framework: • time itself emerges from phase ordering; • coherence preservation allows late-mode selection; • no retrocausality is involved. The outcome reflects final coherence conditions, not past knowledge. --- 8. No collapse, only regime transition There is no physical “collapse”. Instead, there is: • a transition from distributed coherence to localized resonance stability; • a change of dynamical regime; • emergence of macroscopic definiteness. Wave → particle transition is micro → macro coherence restructuring. 9. One-sentence synthesis > Wave–particle duality is not a duality of objects, but a duality of coherence regimes in the S-field. --- 10. Conceptual closure This interpretation: • removes observer-dependence; • preserves realism; • unifies wave and particle behavior dynamically; • aligns quantum phenomena with micro–macro transition theory.
