    Holography and Emergence.Nicholas J. Teh - 2013 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 44 (3):300-311.
    In this paper, I discuss one form of the idea that spacetime and gravity might ‘emerge’ from quantum theory, i.e. via a holographic duality, and in particular via AdS/CFT duality. I begin by giving a survey of the general notion of duality, as well as its connection to emergence. I then review the AdS/CFT duality and proceed to discuss emergence in this context. We will see that it is difficult to find compelling arguments for the emergence of full quantum gravity (...)

    Galileo’s Gauge: Understanding the Empirical Significance of Gauge Symmetry.Nicholas J. Teh - 2016 - Philosophy of Science 83 (1):93-118.
    This article investigates and resolves the question whether gauge symmetry can display analogs of the famous Galileo’s ship scenario. In doing so, it builds on and clarifies the work of Greaves and Wallace on this subject.

    Theoretical Equivalence in Classical Mechanics and its Relationship to Duality.Nicholas J. Teh & Dimitris Tsementzis - 2017 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 59:44-54.
    As a prolegomenon to understanding the sense in which dualities are theoretical equivalences, we investigate the intuitive `equivalence' of hyper-regular Lagrangian and Hamiltonian classical mechanics. We show that the symplectification of these theories provides a sense in which they are isomorphic, and mutually and canonically definable through an analog of `common definitional extension'.

    Recovering Recovery: On the Relationship Between Gauge Symmetry and Trautman Recovery.Nicholas J. Teh - 2018 - Philosophy of Science 85 (2):201-224.
    This article uncovers a foundational relationship between the ‘gauge symmetry’ of a Newton-Cartan theory and the celebrated Trautman Recovery Theorem and explores its implications for recent philosophical work on Newton-Cartan gravitation.

    Gravity and Gauge.Nicholas J. Teh - 2016 - British Journal for the Philosophy of Science 67 (2):497-530.
    Philosophers of physics and physicists have long been intrigued by the analogies and disanalogies between gravitational theories and gauge theories. Indeed, repeated attempts to collapse these disanalogies have made us acutely aware that there are fairly general obstacles to doing so. Nonetheless, there is a special case space-time dimensions) in which gravity is often claimed to be identical to a gauge theory. I subject this claim to philosophical scrutiny in this article. In particular, I analyse how the standard disanalogies can (...)

    A Note on Rovelli’s ‘Why Gauge?’.Nicholas J. Teh - 2015 - European Journal for Philosophy of Science 5 (3):339-348.
    Rovelli’s “Why Gauge?” offers a parable to show that gauge-dependent quantities have a modal and relational physical significance. We subject the morals of this parable to philosophical scrutiny and argue that, while Rovelli’s main point stands, there are important disanalogies between his parable and Yang-Mills type gauge theory.

    Newtonian Equivalence Principles.James Read & Nicholas J. Teh - forthcoming - Erkenntnis:1-25.
    The equivalence principle has constituted one of the cornerstones of discussions in the foundations of spacetime theories over the past century. However, up to this point the principle has been considered overwhelmingly only within the context of relativistic physics. In this article, we demonstrate that the principle has much broader, super-theoretic significance: to do so, we present a unified framework for understanding the principle in its various guises, applicable to both relativistic and Newtonian contexts. We thereby deepen significantly our understanding (...)

    Relational Realism: A New Foundation for Quantum Mechanics?: Michael Epperson and Elias Zafiris: Foundations of Relational Realism: A Topological Approach to Quantum Mechanics and the Philosophy of Nature. Lanham, Maryland: Lexington Books, 2013, Xviii+419pp, $101.28 HB.Nicholas J. Teh - 2015 - Metascience 24 (2):205-209.
    Foundations of Relational Realism: A Topological Approach to Quantum Mechanics and the Philosophy of Nature by Michael Epperson and Elias Zafiris sets out to achieve three goals: to develop a version of Whiteheadian metaphysics that the authors call “relational realism”; to formalize relational realism in terms of category theory, in particular sheaf theory; and to use relational realism to solve the interpretative problems of quantum mechanics. These goals are ambitious, to say the least, and all this is leaving aside those (...)

    Classical Cloning and No-Cloning.Nicholas J. Teh - unknown
    It is part of information theory folklore that, while quantum theory prohibits the generic cloning of states, such cloning is allowed by classical information theory. Indeed, many take the phenomenon of no-cloning to be one of the features that distinguishes quantum mechanics from classical mechanics. In this paper, we use symplectic geometry to argue that pace conventional wisdom, in the case where one does not include a machine system, there is an analog of the no-cloning theorem for classical systems. However, (...)

  13. Edge Modes and Dressing Fields for the Newton–Cartan Quantum Hall Effect.Nicholas J. Teh, James Read & William J. Wolf - 2022 - Foundations of Physics 53 (1):1-24.
    AbstractIt is now well-known that Newton–Cartan theory is the correct geometrical setting for modelling the quantum Hall effect. In addition, in recent years edge modes for the Newton–Cartan quantum Hall effect have been derived. However, the existence of these edge modes has, as of yet, been derived using only orthodox methodologies involving the breaking of gauge-invariance; it would be preferable to derive the existence of such edge modes in a gauge-invariant manner. In this article, we employ recent work by Donnelly (...)
