  1. Complexity Biology-based Information Structures can explain Subjectivity, Objective Reduction of Wave Packets, and Non-Computability.Alex Hankey - 2014 - Cosmos and History 10 (1):237-250.
    Background: how mind functions is subject to continuing scientific discussion. A simplistic approach says that, since no convincing way has been found to model subjective experience, mind cannot exist. A second holds that, since mind cannot be described by classical physics, it must be described by quantum physics. Another perspective concerns mind's hypothesized ability to interact with the world of quanta: it should be responsible for reduction of quantum wave packets; physics producing 'Objective Reduction' is (...)

    Wave packet reduction in quantum mechanics: A model of a measuring apparatus. [REVIEW]M. Cini, M. De Maria, G. Mattioli & F. Nicolò - 1979 - Foundations of Physics 9 (7-8):479-500.
    We investigate the problem of “wave packet reduction” in quantum mechanics by solving the Schrödinger equation for a system composed of a model measuring apparatusM interacting with a microscopic objects. The “instrument” is intended to be somewhat more realistic than others previously proposed, but at the same time still simple enough to lead to an explicit solution for the time-dependent density matrix. It turns out that,practically, everything happens as if the wave packet reduction had occurred. This (...)

    Proposed experimental test of wave packet reduction and the uncertainty principle.E. E. Fitchard - 1979 - Foundations of Physics 9 (7-8):525-535.
    A practical experiment using coincidence techniques is suggested to test the validity of the following concepts:(1) wave packet reduction and(2) the measurement-uncertainty principle for position and momentum. The suggested experiment uses the time-of-flight method to determine an electron's momentum and a coincident photon, emitted from a system excited by the electron, to determine its initial position. It is shown that this method does constitute a simultaneous measurement of position and momentum for a single system. Also, it is pointed (...)

    Wave-packet reduction as a medium of communication.Joseph Hall, Christopher Kim, Brien McElroy & Abner Shimony - 1977 - Foundations of Physics 7 (9-10):759-767.
    Using an apparatus in which two scalers register decays from a radioactive source, an observer located near one of the scalers attempted to convey a message to an observer located near the other one by choosing to look or to refrain from looking at his scaler. The results indicate that no message was conveyed. Doubt is thereby thrown upon the hypothesis that the reduction of the wave packet is due to the interaction of the physical apparatus with the (...)

  5. Orchestrated objective reduction of quantum coherence in brain microtubules: The "orch OR" model for consciousness.Roger Penrose & Stuart Hameroff - 1996 - Mathematics and Computers in Simulation 40:453-480.
    Features of consciousness difficult to understand in terms of conventional neuroscience have evoked application of quantum theory, which describes the fundamental behavior of matter and energy. In this paper we propose that aspects of quantum theory (e.g. quantum coherence) and of a newly proposed physical phenomenon of quantum wave function "self-collapse"(objective reduction: OR -Penrose, 1994) are essential for consciousness, and occur in cytoskeletal microtubules and other structures within each of the brain's neurons. The particular characteristics of microtubules (...)

  6. The aharonov-Bohm effect and the reality of wave packets.Chuang Liu - 1994 - British Journal for the Philosophy of Science 45 (4):977-1000.
    The objective of this paper is to show that, instead of quantum probabilities, wave packets are physically real. First, Cartwright's recent argument for the reality of quantum probabilities is criticized. Then, the notion of ‘physically real’ is precisely defined and the difference between wave functions and quantum probabilities clarified. Being thus prepared, some strong reasons are discussed for considering the wave packet to be physically real. Finding the reasons inconclusive, I explain how the Aharonov—Bohm effect (...)

    Pure states, mixtures, and reduction of the wave packet.J. Andrade E. Silva - 1972 - Foundations of Physics 2 (4):245-256.
    The usual distinction in quantum mechanics between pure states and mixtures is shown not to be independent of the interpretation adopted. Thus, in a causal theory, certain states should be regarded as sharing the nature of both pure states and mixtures and, as a result, important questions in the theory of measurement must be considered in a different light.

  8. Does consciousness collapse the wave-packet?Dick Bierman - 2003 - Mind and Matter 1 (1):45-57.
    The 'subjective reduction' interpretation of measurement in quantum physics proposes that the collapse of the wave-packet, associated with measurement, is due to the consciousness of human observers. A refined conceptual replication of an earlier experiment, designed and carried out to test this interpretation in the 1970s, is reported. Two improvements are introduced. First, the delay between pre-observation and final observation of the same quantum event is increased from a few microseconds in the original experiment to one second in (...)

    Compatible statistical interpretation of a wave packet.Mirjana Božić & Zvonko Marić - 1995 - Foundations of Physics 25 (1):159-173.
    A compatible statistical interpretation of a wave packet is proposed. De Broglian probabilities which unite wave and particle features of quantons are evaluated for free wave packets and Jor a superposition of wave packets. The obtained expressions provide a very plausible and physically appealing explanation of coherence in apparently incoherent beams and of the characteristic modulation of the momentum distribution, found recently in neutron interferometry combined with spectral filtering. Certain conclusions about dualism and objectivity (...)

    Many-Hilbert-spaces theory of quantum measurements.Mikio Namiki - 1988 - Foundations of Physics 18 (1):29-55.
    The many-Hilbert-spaces theory of quantum measurements, which was originally proposed by S. Machida and the present author, is reviewed and developed. Dividing a typical quantum measurement in two successive steps, the first being responsible for spectral decomposition and the second for detection, we point out that the wave packet reduction by measurement takes place at the latter step, through interaction of an object system with one of the local systems of detectors. First we discuss the physics of the (...)

  11. Missing Elements and Missing Premises: A Combinatorial Argument for the Ontological Reduction of Chemistry.Robin Le Poidevin - 2005 - British Journal for the Philosophy of Science 56 (1):117-134.
    Does chemistry reduce to physics? If this means ‘Can we derive the laws of chemistry from the laws of physics?’, recent discussions suggest that the answer is ‘no’. But sup posing that kind of reduction—‘epistemological reduction’—to be impossible, the thesis of ontological reduction may still be true: that chemical properties are determined by more fundamental properties. However, even this thesis is threatened by some objections to the physicalist programme in the philosophy of mind, objections that generalize to (...)

    Convex optimization for additive noise reduction in quantitative complex object wave retrieval using compressive off-axis digital holographic imaging.Anith Nelleri & B. Lokesh Reddy - 2022 - Journal of Intelligent Systems 31 (1):706-715.
    Image denoising is one of the important problems in the research field of computer vision, artificial intelligence, 3D vision, and image processing, where the fundamental aim is to recover the original image features from a noisy contaminated image. The camera sensor additive noise present in the holographic recording process reduces the quality of the retrieved image. Even though various techniques have been developed to minimize the noise in digital holography, the noise reduction still remains a challenging task. This article (...)

    Local Measurements of Nonlocal Observables and the Relativistic Reduction Process.GianCarlo Ghirardi - 2000 - Foundations of Physics 30 (9):1337-1385.
    In this paper we reconsider the constraints which are imposed by relativistic requirements to any model of dynamical reduction. We review the debate on the subject and we call attention on the fundamental contributions by Aharonov and Albert. Having done this we present a new formulation, which is much simpler and more apt for our analysis, of the proposal put forward by these authors to perform measurements of nonlocal observables by means of local interactions and detections. We take into (...)

  14. Reduction: Models of cross-scientific relations and their implications for the psychology-neuroscience interface.Robert McCauley - manuscript
    University Abstract Philosophers have sought to improve upon the logical empiricists’ model of scientific reduction. While opportunities for integration between the cognitive and the neural sciences have increased, most philosophers, appealing to the multiple realizability of mental states and the irreducibility of consciousness, object to psychoneural reduction. New Wave reductionists offer a continuum of comparative goodness of intertheoretic mapping for assessing reductions. Their insistence on a unified view of intertheoretic relations obscures epistemically significant crossscientific relations and engenders (...)

    We argue in this paper that so-called new wave reductionism fails to capture the nature of the interlevel relations between psychology and neuroscience.

    Time development of a wave packet and the time delay.Hiromichi Nakazato - 1997 - Foundations of Physics 27 (12):1709-1723.
    A one-dimensional scattering problem off a δ-shaped potential is solved analytically and the time development of a wave packet is derived from the time-dependent Schrödinger equation. The exact and explicit expression of the scattered wave packet supplies us with interesting information about the “time delay” by potential scattering in the asymptotic region. It is demonstrated that a wave packet scattered by a spin-flipping potential can give us quite a different value for the delay times from that obtained (...)

    Spontaneous localizations of the wave function and classical behavior.Andor Frenkel - 1990 - Foundations of Physics 20 (2):159-188.
    We investigate and develop further two models, the GRW model and the K model, in which the Schrödinger evolution of the wave function is spontaneously and repeatedly interrupted by random, approximate localizations, also called “self-reductions” below. In these models the center of mass of a macroscopic solid body is well localized even if one disregards the interactions with the environment. The motion of the body shows a small departure from the classical motion. We discuss the prospects and the difficulties (...)

    A nondispersive de Broglie wave packet.L. Mackinnon - 1978 - Foundations of Physics 8 (3-4):157-176.
    It is assumed that the motion of a particle in spacetime does not depend on the motion relative to it of any observer or of any frame of reference. Thus if the particle has an internal vibration of the type hypothesized by de Broglie, the phase of that vibration at any point in spacetime must appear to be the same to all observers, i.e., the same in all frames of reference. Each observer or reference frame will have its own de (...)

    Wigner trajectories of a Gaussian wave packet perturbed by a weak potential.Hai-Woong Lee - 1992 - Foundations of Physics 22 (8):995-1010.
    Trajectories along which phase-space points of the Wigner distribution function move are computed for a Gaussian wave packet moving under the influence of a weak perturbative potential. The potentials considered are a potential step, a potential barrier, and a periodic potential. Trajectories computed exhibit the complex, nonlocal nature of quantum dynamics. It is seen that quantum interference, which takes place in the time development of the wave packet, is taken care of in a simple way by the Wigner (...)

    The de Broglie wave packet for a simple stationary state.L. Mackinnon - 1979 - Foundations of Physics 9 (9-10):787-791.
    A simple stationary state is set up by combining the two de Broglie waves from two particles traveling in one direction with equal and opposite velocities. By considering the waves forming this state from the point of view of all possible observers moving in the same direction, it is shown that the basic standing wave pattern does not alter, but that the particle will be confined to a small region stationary relative to this pattern. This region is similar in (...)

  39. Psychoneural Reduction: The New Wave.John W. Bickle - 1998 - Bradford.
    One of the central problems in the philosophy of psychology is an updated version of the old mind-body problem: how levels of theories in the behavioral and brain sciences relate to one another. Many contemporary philosophers of mind believe that cognitive-psychological theories are not reducible to neurological theories. However, this antireductionism has not spawned a revival of dualism. Instead, most nonreductive physicalists prefer the idea of a one-way dependence of the mental on the physical.In Psychoneural Reduction, John Bickle presents (...)

    The concept of transition in quantum mechanics.James L. Park - 1970 - Foundations of Physics 1 (1):23-33.
    The concept of quantum transition is critically examined from the perspective of the modern quantum theory of measurement. Historically rooted in the famous quantum jump of the Old Quantum Theory, the transition idea survives today in experimental jargon due to (1) the notion of uncontrollable disturbance of a system by measurement operations and (2) the wave-packet reduction hypothesis in several forms. Explicit counterexamples to both (1) and (2) are presented in terms of quantum measurement theory. It is concluded (...)

    The principle that causes always render their effects more likely is fundamental to the enterprise of reducing facts of causation to facts about (objective) chances. This reductionist enterprise faces famous difficulties in accommodating common-sense intuitions about causal processes, if it insists on cashing out causal processes in terms of streams of events in which every event that belongs to the stream is a cause of the adjoining event downstream of it. I shall propose modifications to this way of cashing (...)

    A Numerical Solution of Ermakov Equation Corresponding to Diffusion Interpretation of Wave Mechanics.Victor Christianto & Florentin Smarandache - manuscript
    It has been long known that a year after Schrödinger published his equation, Madelung also published a hydrodynamics version of Schrödinger equation. Quantum diffusion is studied via dissipative Madelung hydrodynamics. Initially the wave packet spreads ballistically, than passes for an instant through normal diffusion and later tends asymptotically to a sub‐diffusive law. In this paper we will review two different approaches, including Madelung hydrodynamics and also Bohm potential. Madelung formulation leads to diffusion interpretation, which after a generalization yields to (...)

    Reduction of finite and infinite derivations.G. Mints - 2000 - Annals of Pure and Applied Logic 104 (1-3):167-188.
    We present a general schema of easy normalization proofs for finite systems S like first-order arithmetic or subsystems of analysis, which have good infinitary counterparts S ∞ . We consider a new system S ∞ + with essentially the same rules as S ∞ but different derivable objects: a derivation d∈S ∞ + of a sequent Γ contains a derivation Φ∈S of Γ . Three simple conditions on Φ including a normal form theorem for S ∞ + easily imply a (...)

    The inferences of common causes reduced to common origins.Aviezer Tucker - 2020 - Studies in History and Philosophy of Science Part A 81:105-115.
    This paper advocates the reduction of the inference of common cause to that of common origins. It distinguishes and subjects to critical analysis thirteen interpretations of “the inference of common cause” whose conclusions do not follow from their assumptions. Instead, I introduce six types of inferences of common origins of information signals from their receivers to reduce, in the sense of supersede and replace, the thirteen inferences of common causes. I show how the paradigmatic examples of inferences of common (...)

    Mandelstam's interpretation of quantum mechanics in comparative perspective.A. A. Pechenkin - 2002 - International Studies in the Philosophy of Science 16 (3):265 – 284.
    In his 1939 Lectures, the prominent Soviet physicist L. I. Mandelstam proposed an interpretation of quantum mechanics that was understood in different ways. To assess Mandelstam's interpretation, we classify contemporary interpretations of quantum mechanics and compare his interpretation with others developed in the 1930s. We conclude that Mandelstam's interpretation belongs to the family of minimal statistical interpretations and has much in common with interpretations developed by American physicists. Mandelstam's characteristic message was his theory of indirect measurement, which influenced his discussion (...)

    Wave-Particle Duality and the Objectiveness of “True” and “False”.Arkady Bolotin - 2021 - Foundations of Physics 51 (4):1-27.
    The traditional analysis of the basic version of the double-slit experiment leads to the conclusion that wave-particle duality is a fundamental fact of nature. However, such a conclusion means to imply that we are not only required to have two contradictory pictures of reality but also compelled to abandon the objectiveness of the truth values, “true” and “false”. Yet, even if we could accept wave-like behavior of quantum particles as the best explanation for the build-up of an interference (...)

    The paradox of two bottles in quantum mechanics.Bogdan Mielnik - 1990 - Foundations of Physics 20 (6):745-755.
    A class of retrospective measurements analogous to the “delayed choice experiments” of Wheeler and Greenberger is considered. A new argument shows that the reduction of the wave packet must affect the past states of the system. As a side product, our argument implies that the axiom about the reduction of the wave packet in relativistic space-time cannot be consistently introduced.
