Paper 60B develops a unified Holosphere account of the double-slit experiment while keeping interference loss, measurement, and stable outcome formation conceptually separate. The paper begins with standard slit-resolved paraxial propagation and shows that a coherent two-slit pattern contains a cross term that is absent from the incoherent sum of the two single-slit diffraction patterns. Which-path detection is modeled through the overlap of path-dependent detector states. As those detector states become more distinguishable, fringe visibility decreases continuously and reaches the incoherent limit when the path records are fully distinguishable. The Holosphere interpretation treats a coherence corridor as a physical relation among the source, carrier, aperture, detector, environment, and readout boundary. The apparatus therefore helps determine whether the two paths remain part of one coherence-supporting structure. Boundary incompatibility separates path-conditioned corridors, while later interface competition and pointer-basin capture may select and stabilize a detector record. Physical recoil and apparatus relaxation remain causal, and no faster-than-light signal or strict determinism is required. A separate downstream phase-edge gate produces a modest, symmetric, and resolution-surviving change in the screen distribution. The numerical suite also verifies symmetry, attenuation accounting, slit-field linearity, detector-overlap behavior, and the conditioned quantum-eraser identity.

The double-slit experiment is often framed as evidence that microscopic objects are “both waves and particles,” or that a wavefunction “collapses” upon measurement. This paper gives a QMU-native, apparatus-centric explanation in the Aether Physics Model (APM) by separating the experiment into three operational layers: (1) Transport layer (space): Light is treated as a conserved transport content, denoted here as ligt, distributed over expanding photon fronts. The measurable quantity in space is the delivered areal density (intensity) lint(ν;r). Interference is asserted at this transport layer: two outgoing channels can superpose and form stable bright and dark regions in lint at the screen plane before any detection event occurs. (2) Boundary layer (aperture): The slit-mask is modeled as a transfer operator T acting on the incident delivery density:lintout(ν;r)=Tlintin(ν;r).For a double slit, the outgoing density is produced by two transfer channels, T1 and T2, whose superposition yields an intensity-level interference formlinttot(P)=lint1(P)+lint2(P)+2lint1(P)lint2(P)cosΔϕ(P).The phase difference is written in QMU-normalized form using the chronovibration identity and the dimensionless cadence:c=FqλC,ν∗=Fqν,λ=ν∗λC,so thatΔϕ(P)=2πλΔℓ(P)=2πν∗λCΔℓ(P).In the far-field approximation with slit separation d, screen distance L, and transverse coordinate x, Δℓ(x)≈dx/L, givingΔϕ(x)≈2πν∗LdλCx.This emphasizes that the fringe map is a geometric count in units of λC scaled by the dimensionless cadence ν∗. (3) Detection layer (matter): Detection is a discrete resonance gate event in matter, not a continuous “field readout.” The receiver is represented by a binary acceptance functionG(ν∗,alignment)∈{0,1},and the event-rate density follows the gated effective drivelinteff(r)=∫G(ν∗,alignment)R(ν∗)lint(ν;r)dν,N˙e(r)∝linteff(r).Single-particle hits therefore build the fringe pattern because discrete events sample a pre-existing transport interference pattern in lint. Coherence window and a falsifiable fringe condition The paper introduces a receiver coherence window τg and its QMU-normalized form τg∗=Fqτg. This produces a detector gate coherence lengthLg=cτg=λCτg∗,and a direct, falsifiable interference conditionΔℓ(P)≲λCτg∗.A key operational refinement is the \emph{minimum law} for the observed visibility rolloff length:Lrolloff≈min(Lc,Lg),where Lc is a transport coherence length set by source bandwidth / wavefront quality, and Lg is the detector’s gate coherence length. This predicts two distinct regimes and a detector-dependent saturation plateau when Lc is increased beyond Lg. Which-path marking as controlled timing-jitter injection Which-path devices are treated as measurable degradations (timing/phase jitter, alignment scrambling, or mode partitioning), not metaphysical collapse. A minimal quantitative model treats marking as injecting an RMS delay σt between channels, with QMU-normalized jitter σt∗=Fqσt. For Gaussian jitter, the visibility obeysV=V0exp[−2π2(ν∗)2(σt∗)2],yielding a clean functional form for tunable weak-to-strong marking protocols. Slit-edge participation and QMU surface knobs (including qsfo) To make boundary participation experimentally reportable, the slit transfer operator is decomposed asT=Tgeom+Tsurf,where Tsurf captures mask material / coating / roughness / polarization-sensitive surface channels. The paper introduces QMU-native surface oscillation knobs:qsfo:=λCc3=λC2Fq3,qsfi:=c3λC=qsfo1,and defines a dimensionless surface-participation ratioΠsurf:=Ωsurfqsfi,so that “edge effects” are reported as measured QMU parameters rather than qualitative caveats.

This article presents a conceptual and experimentally illustrated reinterpretation of the double-slit experiment based on energetic coherence and Δφ-modulation within the Ilefos Model. Using a classical optical setup—including a 532 nm laser, multi-aperture plates, and photodiode detectors—the study investigates how interference patterns transform under different geometrical and observational conditions. Three coherence regimes are documented: (1) baseline interference, (2) complex multi-aperture diffraction, and (3) speckle-pattern coherence under polarization. The results demonstrate how small structural changes in the optical path lead to significant reorganizations of the field’s coherence distribution, supporting the hypothesis that measurement effects may be interpreted as field participation rather than particle-path detection. While the experiment operates in the classical regime (milliwatt intensities, not single photons), the illustrated coherence transitions align with the theoretical Δφ-framework describing how structured energy patterns respond to constraints and observation. This publication serves as a pilot study for future work involving higher-sensitivity detectors and single-photon sources, and provides a conceptual bridge between classical interference behavior and coherence-based interpretations of quantum measurement.
The double-slit experiment combines three observational facts: interference fringes in the coherent regime, position-resolved detections, and continuous fringe suppression under which-path resolution. Standard quantum mechanics accommodates all three through postulates without deriving them from deeper structure. This paper shows that the standard far-field interference law and the coherence-to-which-path transition follow as structural corollaries of results established in Quantum Mechanics as the Boundary Algebra of a Non-Invertible Projection (doi:10.5281/zenodo.19535588) and its companion (doi:10.5281/zenodo.19571321). Two results suffice for the algebraic derivation: the Born rule as the canonical quadratic measure on Im(Π), and the kernel spinor as the Hilbert quadrature of the boundary field. A third result — measurement irreversibility as a kinematic consequence of the projection geometry — belongs to the physical interpretation of measurement and temporal ordering within the same framework. The paper derives the Fraunhofer intensity law I(x) ∝ |Ψ₁ + Ψ₂|² and the detector-overlap formula with fringe visibility V = |γ|, within the standard Fraunhofer approximation and without additional postulates. It does not claim a first-principles derivation of the full boundary propagator or of single-event arrival statistics. A companion numerical simulation implements all three coherence regimes. A self-contained appendix summarises the three imported results in compact form.
Quantum interference is conventionally formulated using complex amplitudes associated with quantum alternatives or through Feynman’s path integral over possible trajectories. This article investigates a different ontology, the Single-History Record Framework (SHRF), in which a physical system has one realized history together with a record space of phase-carrying contributions associated with that history. Observable amplitudes are obtained through History-Record Summation (HRS). SHRF deliberately retains established quantum ingredients wherever possible, including complex-amplitude addition, the Born probability rule, propagation phases, and marker-state overlaps. These mathematical devices are used as predictive rules and do not imply that multiple physical histories, paths, or marker outcomes coexist.A preliminary model is developed in which rapidly varying regions of record space largely cancel while coherent record bands provide the dominant detector amplitude. For double-slit geometry, two aperture-selected bands give A(x)≈H_A (x)+H_B (x).With the established propagation phases H_A=Ce^(ikL_A ),H_B=Ce^(ikL_B ),SHRF recovers the textbook far-field fringe spacing Δx=λD/d.The same formal structure is applied to single-slit diffraction, multiple slits, which-path marking, partial distinguishability, and quantum-eraser subensembles. In particular, marker records modify the interference term through the standard overlap factor ⟨M_A∣M_B⟩,without requiring a physical superposition of marker records. The present model assumes rather than derives its phase law, record-space measure, and Born rule. It is therefore a recovery-oriented consistency construction and ontological reinterpretation, not an independent replacement for standard quantum mechanics.
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.
This paper presents the 2013 double-slit experiment "Particle Solution to the Double Slit Experiment" (University of Arizona), together with a more rigorous 2026 reconstruction of the same test. Part I reproduces the original study verbatim. A slit was cut at a dark fringe on Screen 1 and the light was measured on Screen 2 behind it. The detector current behind the dark fringe was 1.4 mA, equal to the 1.4 mA laser-off noise. The result was interpreted as supporting the particle view. Part II specifies a high-precision modular protocol designed to discriminate between dark-fringe occupancy and interference: a common baseline (Module 0), the Screen-1 dark-fringe profile (A), an aperture-width series (B), Screen-2 profiles behind dark and bright apertures (C), an offset scan (D), and a closure map (E). The standard optical-field prediction is frozen before acquisition. If no light is observed on Screen 2 behind the dark-fringe aperture while the bright control transmits, the particle view is supported. If two fringes appear, matching the frozen template, the wave view is supported. Status: Part I includes the original 2013 detector readings. Part II is a prospective protocol; no data have been acquired under it.
