Motion From a Particle's Point of View: an Interpretation of the Double Slit Experiment

Abstract

Traditionally, motion has been defined extrinsically, as the change in the position of an object, such as a particle, over time. This definition presupposes the existence of an external to the particle who measures the position of the particle as a function of time. Yet, in the double slit experiment, we have experimental proof that a particle can travel unobserved between a source and a detector. It does so in such a way that we cannot, even in principle, describe its motion by a position changing in time. We propose that the correct interpretation of this experiment is that the traditional extrinsic definition of motion is incomplete. We propose a more general intrinsic definition of motion, in which the role of observer is played by the particle itself, and which presupposes no external observer. We discuss the double slit experiment including the nature of measurement and the particle-wave duality. We show that using the intrinsic point of view allows us to avoid the weirdness that tends to crop up when these topics are analysed from the extrinsic point of view.

Motion From a Particle's Point of View: Relativistic Mechanics

Blazej Kot

has traditionally been defined extrinsically, as the change in the position of an object, such as a particle, over time. In previous work titled Motion From a Particle's Point of View: An Interpretation of the Double Slit Experiment we argued that this definition of motion is incomplete and that it is using it which leads to the weirdness of quantum mechanics, as exemplified by the double slit experiment. We proposed an alternative intrinsic definition of motion, using which we claimed quantum mechanics can be understood without weirdness. In this paper, we extend this previous work, which only considered constant-speed motion of a single particle, to the case of: first, multiple particles in constant-speed motion; and, second, the case of multiple accelerating, that is, interacting, particles. We show we can in this way recover the key equations and phenomena of both special and general relativity. By showing that the intrinsic definition of motion underlies the theories of special and general relativity, as well as quantum mechanics, we propose it may be of use in developing a theory of quantum gravity.

Alternative Approach to Copenhagen Interpretation

In this study, a double-slit experiment was simulated with only classical-mechanics assumptions to demonstrate that the phenomena associated with this experiment can be explained by classical mechanics. The experiment was conducted with the particle nature intact, by performing observations that did not affect the particle motion while recording the particle position at each simulation step. Only one experimental particle was assumed per session to prevent external effects. Nevertheless, wave patterns, which have previously been thought to occur only quantum-mechanically, were observed on the inspection plate. This study focused on proving that classical mechanics can explain the double-slit wave pattern.

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 Double-Slit Experiment and Particle-Wave Duality: Toward a Novel Quantum Interpretation

Itzhak Orion, Michael Laitman

The double-slit experiment demonstrates the quantum physics particle-wave duality problem. Over the last decades many interpretations were introduced to the quantum theory perception problem. In most cases there was use of unclear terms, or obscure processes in these interpretations, such as particle splitting. In this paper we propose a novel concept to explain the experiment based on two postulates: The Equivalence of Form (EoF), and the particles connection to other particles, effectively functioning as a group. These two condi-tions are necessary to maintain wave qualities in the collective relations, and therefore cannot exist in a sin-gle particle. De Broglie introduced the mathematical relation of particle to wave; however, he did not specify the conditions for that. The proposed interpretation is a new way of looking at particles as a united group, the Kevutsa, which has a higher order level of matter. A series of identical particles maintain additional qualities to show a large united, correlated motion that we observe as waves transport through systems.

Young's Double-Slit Experiment: "What's Really Happening?"

Nakka Gurappa

A new wave-particle non-dualistic interpretation for the quantum formalism is presented by proving that the Schrödinger wave function is an `{\it instantaneous resonant spatial mode}' in which the quantum particle moves. The probabilities in quantum mechanics arise only for the observer's perspective due to the nature of doing experiments but they do not exist in Nature. In other words, quantum mechanics itself is not a probabilistic theory. This view-point is proved by deriving the Born's rule by showing it to be equal to the experimentally observed relative frequencies. Also, it is shown that the classical and quantum mechanical times are one and the same. By identifying the already inherently existing mechanism for the collapse of wave function within the quantum formalism, the present interpretation naturally proves why the Copenhagen interpretation is very successful in explaining the experimental outcomes. The Young's double-slit experiment, the Wheeler's delayed choice experiment and the Afshar's experiment are unambiguously explained at a single quantum level. Both `measurement problem' and `retrocausality' are absent in the present non-dualistic interpretation of quantum mechanics.
