Abstract:Wave–particle duality remains one of the most conceptually challenging aspects of quantum mechanics. Standard interpretations describe the transition between wave-like and particle-like behavior through complementarity or measurement-induced collapse, but do not specify the underlying mechanism.This work proposes a new interpretation based on Informational Distinguishability (ID): a quantum system behaves as a wave when its possible micro-configurations or paths are informationally indistinguishable, and as a particle when environmental structure renders these configurations distinguishable. The transition corresponds to an informational compression rather than an observer-dependent collapse.The framework naturally explains interference disappearance, quantum erasers, delayed-choice phenomena, and upstream mode switching. It also yields falsifiable predictions, including quantitative thresholds of distinguishability and controlled partial-interference regimes.The model provides a unifying informational foundation for wave–particle behavior and suggests new directions in quantum foundations, measurement theory, and informational physics.

This paper presents a conceptually economical reinterpretation of wave–particle duality, framing it as a consequence of dimensional projection rather than as a fundamental ontological dualism or an observer-induced collapse. Quantum systems are treated as evolving continuously within a space of effective informational degrees of freedom, while particle-like behavior emerges from restricted lower-dimensional access and irreversible recording. By reclassifying classic experiments—such as double-slit interference, delayed-choice setups, quantum erasers, and automated detection—under this framework, the work highlights that their empirically observed continuous behaviors are more naturally explained by projection and information restriction than by abrupt state reduction. Beyond reinterpretation, the paper introduces a falsifiable experimental criterion—the Dimensional Projection Test (DPT)—which distinguishes projection-based, no-collapse descriptions from genuine collapse models. The DPT predicts a smooth degradation of interference visibility under continuously tuned coupling, whereas any sharp transition would signal objective collapse dynamics. Positioned as complementary to existing collapse-model bounds rather than a competing formalism, the DPT provides an operational lens through which foundational ambiguities can be tested experimentally. Overall, the work clarifies long-standing conceptual confusion without modifying quantum mechanics, offering a disciplined, test-oriented contribution to quantum foundations. Reality does not change when we stop observing; only our access does.
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.
This work proposes a minimal ontological framework for interpreting wave–particle duality as a boundary-sensitive manifestation of quantum phenomena on an underlying, physically real but unobservable background. Rather than treating wave-like and particle-like behaviors as competing physical entities, the framework interprets them as distinct modes of manifestation determined by global boundary conditions. Motivated by interference experiments such as the double-slit setup, the study argues that experimental outcomes depend on boundary-induced modifications of a background structure beyond the local particle path. Within this view, wave-like interference corresponds to a nonlocal manifestation shaped by boundary conditions, while particle-like detection corresponds to localized manifestation events at measurement. The proposed interpretation preserves the standard quantum formalism while offering a realist, boundary-centered conceptual perspective that avoids observer-dependent collapse or multi-path particle propagation. The manuscript is provided as a preprint to invite open scientific discussion and critical evaluation.
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.

Quantum mechanics describes physical systems through probabilistic wave functions, accounting for phenomena such as wave–particle duality and the uncertainty principle. Although the mathematical formalism of quantum mechanics is well established, conceptual understanding of how quantum entities transition between wave-like and particle-like behavior remains an active area of research. In this work, quantum mechanical principles are re-examined from an interaction-based perspective, emphasizing the roles of environmental coupling, measurement geometry, and energy exchange. Using the photoelectric effect, de Broglie relations, and Heisenberg’s uncertainty principle as foundational elements, a conceptual framework is proposed in which particle identity emerges dynamically from wave interaction with matter and measurement constraints. This interpretation provides an intuitive bridge between classical reasoning and quantum behavior while fully preserving the standard mathematical structure of quantum mechanics...........Please check the attachment for details
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.
