Wave-particle duality in the asymmetrical double-slit interference experiments

Abstract

Abstract We perform spectral analysis based on suitable theoretical correlations between V-wave visibility and D-particle distinguishability to verify wave-particle duality in the asymmetrical double-slit experiments. The typical interference spectra obtained in a recent experiment ensure the single-photon approximation in the Fraunhofer far-field condition. The results show that our theoretical model following the complementarity principle is not be consistent with the experimental data at the first main minima of the diffraction distribution where unexpected interference was observed

Wave-particle duality in the asymmetrical double-slit interference experiments

Thuan Vo Van, Vinh Vu Duc, Hưng Nguyễn Thành +1 more

Abstract We perform spectral analysis based on a suitable theoretical correlation between V-wave visibility and D-particle distinguishability following the complemen-tarity principle to verify wave-particle duality in the asymmetrical double-slit experiments. The selective interference spectra obtained in the experiments ensure the single-photon approximation in the Fraunhofer far-field condition. The results show that the theoretical interpretation following wave-particle complementarity may not be consistent with the experimental data, especially at the first main minima of the optical diffraction distributions. A dilemma would arise when one tries to revise the theoretical explanations for preserving the complementarity principle.

Asymmetrical double-slit interference for insight into microscopic physical reality

Vo Van Thuan, Vinh Vu Duc, Nguyen Thanh Hung +1 more

abstract We report the findings of asymmetrical double-slit experiments conducted under Fraunhofer far-field conditions, within the single-photon approximation framework. A notable outcome of these experiments is the consistent observation of interference effects at the first main diffraction minima that surpass the limit set by the complementarity principle D + V = 1. Specifically, we identify anomalous correlations between the D-particle distinguishability and the V-wave visibility, where D + V > 1., suggesting that, within the same experimental context, a significant number of photons exhibit both wave-like and particle-like behavior simultaneously. In the absence of a more comprehensive theoretical account, this anomalous interference may serve as empirical support for the objective physical reality of quantum matter, which stands in contrast to the foundational tenets of the Copenhagen school of quantum mechanics.

A Hybrid-Asymmetrical Double-Slit Interference Experiment in the Near-Field Transition Pre-Fraunhofer Condition

Thuan Vo Van, Vinh Vu Duc, Hưng Nguyễn Thành +6 more

Abstract The paper presents the results of a quantum interference study using an asymmetrical double-slit experiment with a low-intensity laser beam, conducted in the single-photon approximation and the Fresnel near-field transition pre-Fraunhofer condition. In addition to the temporal separation achieved by recording each particle individually, the hybrid-asymmetrical double-slit design (in both width and height) also allows spatial separation of the first satellite diffraction bands created by each slit, thereby minimising the mixing background effects from the opposite slit. Isolating the satellite bands of a diffraction pattern from one of the two slits enables which-way identification of the quantum particle, contributing maximally to the path-distinguishability parameter D=1. Within these satellite bands, we observed interference fringes with reliability at their diffraction peaks for the wide slit and the narrow slit. After subtracting multiphoton-mixing interference noises V(mix), we obtain significant single-photon wave visibility values = 0.051±.009(stat.+sys.) and = 0.065±.009(stat.+sys.), respectively, at the wide-slit I1 and narrow-slit I2 diffraction bands. The results suggest the possibility of establishing an unusual correlation, D + V > 1, in which a significant number of photons exhibit both wave and particle properties simultaneously within the same experimental spectrum. This differs from the Copenhagen interpretation and therefore requires further explanation. PACS numbers: 03.65.-w, 03.65.Ta, 42.50.Xa

A Single-Photon Double-Slit Interference Experiment

Sherwood I. Parker

We describe a double-slit interference experiment suitable for a beginning physics laboratory in which single photons are observed to interfere with themselves, directly demonstrating the wave-particle duality. When the photons are tagged to indicate which slit they passed through, the double-slit interference vanishes. Both the slits and the diffraction pattern are visible to the unaided eye.
