    Saad Rfifi & Fatimazahra Siyouri (forthcoming). Effect of Cavity QED on Entanglement. Foundations of Physics:1-10.
    We use a quantum electrodynamics model, to study the evolution of maximally entangled bipartite states, as well as a maximally entangled tripartite states as a multipartite system. Furthermore, we study the entanglement behaviour of these output states in cavity QED as function of interaction time and the coupling strength. The present study discusses the separability and the entanglement limit of such states after interaction with a cavity QED.

    Takayuki Miyadera (forthcoming). Energy-Time Uncertainty Relations in Quantum Measurements. Foundations of Physics:1-29.
    Quantum measurement is a physical process. A system and an apparatus interact for a certain time period, and during this interaction, information about an observable is transferred from the system to the apparatus. In this study, we quantify the energy fluctuation of the quantum apparatus required for this physical process to occur autonomously. We first examine the so-called standard model of measurement, which is free from any non-trivial energy–time uncertainty relation, to find that it needs an external system that switches (...)

    Todd A. Oliynyk (forthcoming). Classical-Quantum Limits. Foundations of Physics:1-22.
    We introduce a new approach to analyzing the interaction between classical and quantum systems that is based on a limiting procedure applied to multi-particle Schrödinger equations. The limit equations obtained by this procedure, which we refer to as the classical-quantum limit, govern the interaction between classical and quantum systems, and they possess many desirable properties that are inherited in the limit from the multi-particle quantum system. As an application, we use the classical-quantum limit equations to identify the source of the (...)

    Fabio Costa & Sally Shrapnel (2016). Quantum Causal Modelling. New Journal of Physics 18 (6):063032.
    Causal modelling provides a powerful set of tools for identifying causal structure from observed correlations. It is well known that such techniques fail for quantum systems, unless one introduces 'spooky' hidden mechanisms. Whether one can produce a genuinely quantum framework in order to discover causal structure remains an open question. Here we introduce a new framework for quantum causal modelling that allows for the discovery of causal structure. We define quantum analogues for core features of classical causal modelling techniques, including (...)

    Isaac Wilhelm, Chaos Regained: On the Possibility of a New Era of Orbital Dynamics.
    In this paper I explore how the nature, scope, and limits of the knowledge obtained in orbital dynamics—the science concerned with the motions of bodies in the solar system—has changed in recent years. Innovations in the design of spacecraft trajectories, as well as in astronomy, have led to a new hybrid of theory and experiment, and suggest that the kind of knowledge achieved in orbital dynamics today is dramatically different from the knowledge achieved prior to those innovations. Thus, orbital dynamics (...)

    Federico Zalamea (2015). The Mathematical Description of a Generic Physical System. Topoi 34:339-348.
    When dealing with a certain class of physical systems, the mathematical characterization of a generic system aims to describe the phase portrait of all its possible states. Because they are defined only up to isomorphism, the mathematical objects involved are ‘‘schematic struc- tures’’. If one imposes the condition that these mathemat- ical definitions completely capture the physical information of a given system, one is led to a strong requirement of individuation for physical states. However, we show there are not enough (...)

    D. Sen (2014). The Uncertainty Relations in Quantum Mechanics. Current Science 107 (7):203-218.
    The notion of uncertainty in the description of a physical system has assumed prodigious importance in the development of quantum theory. Overcoming the early misunderstanding and confusion, the concept grew continuously and still remains an active and fertile research field. Curious new insights and correlations are gained and developed in the process with the introduction of new ‘measures’ of uncertainty or indeterminacy and the development of quantum measurement theory. In this article we intend to reach a fairly uptodate status report (...)

    Charlotte Werndl, Determinism.
    This article focuses on three recent discussions on determinism in the philosophy of science. First, determinism and predictability will be discussed. Then, second, the paper turns to the topic of determinism, indeterminism, observational equivalence and randomness. Finally, third, there will be a discussion about deterministic probabilities. The paper will end with a conclusion.

    Paul Teller, Measurement Accuracy Realism.
    This paper challenges “traditional measurement-accuracy realism”, according to which there are in nature quantities of which concrete systems have definite values. An accurate measurement outcome is one that is close to the value for the quantity measured. For a measurement of the temperature of some water to be accurate in this sense requires that there be this temperature. But there isn’t. Not because there are no quantities “out there in nature” but because the term ‘the temperature of this water’ fails (...)

    Ray Scott Percival (2000). Bergson: Challenger to Einstein's Theory of Time. [REVIEW] Times Higher Education:1 - 2.
    Henri Bergson is perhaps most remembered for his bold challenge to Einstein's theory of the relativity of simultaneity. Bergson maintained that Einstein's theory did not cope with our intuition of time, which is an intuition of duration. Einstein retorted that there may be psychological time, but there is no special philosopher's time. For Einstein, time forms the fourth dimension of a so-called Parmenidean "block universe". I argue that we must be on our guard not to read into the work of (...)

    Sean M. Carroll (forthcoming). In What Sense Is the Early Universe Fine-Tuned? In Barry Loewer, Brad Weslake & Eric Winsberg (eds.), Time's Arrows and the Probability Structure of the World. Harvard University Press
    It is commonplace in discussions of modern cosmology to assert that the early universe began in a special state. Conventionally, cosmologists characterize this fine-tuning in terms of the horizon and flatness problems. I argue that the fine-tuning is real, but these problems aren't the best way to think about it: causal disconnection of separated regions isn't the real problem, and flatness isn't a problem at all. Fine-tuning is better understood in terms of a measure on the space of trajectories: given (...)

    A longstanding issue in attempts to understand the Everett (Many-Worlds) approach to quantum mechanics is the origin of the Born rule: why is the probability given by the square of the amplitude? Following Vaidman, we note that observers are in a position of self-locating uncertainty during the period between the branches of the wave function splitting via decoherence and the observer registering the outcome of the measurement. In this period it is tempting to regard each branch as equiprobable, but we (...)

    We provide a derivation of the Born Rule in the context of the Everett (Many-Worlds) approach to quantum mechanics. Our argument is based on the idea of self-locating uncertainty: in the period between the wave function branching via decoherence and an observer registering the outcome of the measurement, that observer can know the state of the universe precisely without knowing which branch they are on. We show that there is a uniquely rational way to apportion credence in such cases, which (...)

    The concept of living has changed in time along the history of biology and its specificity has been associated or to a particular matter, active such as the chemical one, or was considered as a product of the spatial organization of a passive matter. Today, these two paths can be merged in the chemical perspective that takes account of the general reflections on the complexity and on the systemic, in the “systemic complexity” approach.

    This is an attempt to take a look at chemistry from the point of view of practical realism. Besides its social–historical and normative aspects, the latter involves a direct reference to experimental research. According to Edward Caldin chemistry depends on our being able to isolate pure substances with reproducible properties. Thus, the very basis of chemistry is practical. Even the laws of chemistry are not stable but are subject to correction. At the same time, these statements do not necessarily make (...)

    In this paper we use the framework of generalized probabilistic theories to present two sets of basic assumptions, called axioms, for which we show that they lead to the Hilbert space formulation of quantum mechanics. The key results in this derivation are the co-ordinatization of generalized geometries and a theorem of Solér which characterizes Hilbert spaces among the orthomodular spaces. A generalized Wigner theorem is applied to reduce some of the assumptions of Solér’s theorem to the theory of symmetry in (...)

The possibility to provide an unifying explanation of dark matter and dark energy as phenomena linked with the fluctuations of the three-dimensional quantum vacuum is explored. The changes and fluctuations of the quantum vacuum energy density generate a curvature of space–time similar to the curvature produced by a “dark energy” density.

    Stereochemistry studies molecules and molecular transformations by way of the classical model of the molecule, which envisages molecules as composed of atoms that are linked together by chemical bonds. The underlying hypothesis of this model is that molecules are entities with definite shape and structure, and behave like mechanical objects in the world of possible experience. Such a view of molecules raises questions about the legitimacy of this science because neither shape nor structure is taken any longer as a solid (...)

Its main task is to reflect on what chemists do, in their actual practice; not to bother with an ontological strawman, the fictional derivation from physics. As an autonomous science, chemistry has its own iconic language. Do diagrams, structural formulas, molecular models, and their mental images draw upon tacit knowledge?

    Quentin Ruyant, Primitive Ontology or Primitive Relations?
    Primitive ontology is a program which seeks to make explicit the ontological commitments of physical theories in terms of a distribution of matter in ordinary space-time. This program targets wave-function realism, which interprets the high-dimensional configuration space on which wave-functions are defined as our fundamental physical space. Wave-function realism allegedly fails to account for a correspondence between the ontology it postulates and the ‘manifest image’ of the world in which experimental tests of the theory are performed, and therefore the wave-function (...)

    Born’s quantum probability rule is traditionally included among the quantum postulates as being given by the squared amplitude projection of a measured state over a prepared state, or else as a trace formula for density operators. Both Gleason’s theorem and Busch’s theorem derive the quantum probability rule starting from very general assumptions about probability measures. Remarkably, Gleason’s theorem holds only under the physically unsound restriction that the dimension of the underlying Hilbert space \ must be larger than two. Busch’s theorem (...)

    Matias Slavov (2016). Empiricism and Relationism Intertwined: Hume and Einstein’s Special Theory of Relativity. Theoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 31 (2):247-263.
    Einstein acknowledged that his reading of Hume influenced the development of his special theory of relativity. In this article, I juxtapose Hume’s philosophy with Einstein’s philosophical analysis related to his special relativity. I argue that there are two common points to be found in their writings, namely an empiricist theory of ideas and concepts, and a relationist ontology regarding space and time. The main thesis of this article is that these two points are intertwined in Hume and Einstein.

    Christine C. Dantas (forthcoming). An Inhomogeneous Space–Time Patching Model Based on a Nonlocal and Nonlinear Schrödinger Equation. Foundations of Physics:1-24.
    We consider an integrable, nonlocal and nonlinear, Schrödinger equation as a model for building space–time patchings in inhomogeneous loop quantum cosmology. We briefly review exact solutions of the NNSE, specially those obtained through “geometric equivalence” methods. Furthemore, we argue that the integrability of the NNSE could be linked to consistency conditions derived from LQC, under the assumption that the patchwork dynamics behaves as an integrable many-body system.

    Massimo Tessarotto, Michael Mond & Davide Batic (forthcoming). Hamiltonian Structure of the Schrödinger Classical Dynamical System. Foundations of Physics:1-41.
    The connection between quantum mechanics and classical statistical mechanics has motivated in the past the representation of the Schrödinger quantum-wave equation in terms of “projections” onto the quantum configuration space of suitable phase-space asymptotic kinetic models. This feature has suggested the search of a possible exact super-dimensional classical dynamical system, denoted as Schrödinger CDS, which uniquely determines the time-evolution of the underlying quantum state describing a set of N like and mutually interacting quantum particles. In this paper the realization of (...)

    Kimberly K. Boddy, Sean M. Carroll & Jason Pollack (2016). De Sitter Space Without Dynamical Quantum Fluctuations. Foundations of Physics 46 (6):702-735.
    We argue that, under certain plausible assumptions, de Sitter space settles into a quiescent vacuum in which there are no dynamical quantum fluctuations. Such fluctuations require either an evolving microstate, or time-dependent histories of out-of-equilibrium recording devices, which we argue are absent in stationary states. For a massive scalar field in a fixed de Sitter background, the cosmic no-hair theorem implies that the state of the patch approaches the vacuum, where there are no fluctuations. We argue that an analogous conclusion (...)

    O. Cristi Stoica & Iulian D. Toader (forthcoming). Spacetime Singularities and Invariance. Belgrade Philosophical Annual.
    This paper discusses a novel approach to singularities, based on a recent extension of general relativity that shows why singularities do not constitute a breakdown of physical laws: it is not only the case that physical laws are valid, but they also remain invariant at singularities. The paper describes this kind of invariance, and draws its consequences for our understanding of equivalence in general relativity. In particular, it points out that the difference between the metrics at singularities and those outside (...)

    Michael J. Shaffer (forthcoming). Lakatos’ Quasi-Empiricism in the Philosophy of Mathematics. Polish Journal of Philosophy.
    Imre Lakatos' views on the philosophy of mathematics are important and they have often been underappreciated. The most obvious lacuna in this respect is the lack of detailed discussion and analysis of his 1976a paper and its implications for the methodology of mathematics, particularly its implications with respect to argumentation and the matter of how truths are established in mathematics. The most important themes that run through his work on the philosophy of mathematics and which culminate in the 1976a paper (...)
