    Gauge and Ghosts.Guy Hetzroni - 2021 - British Journal for the Philosophy of Science 72 (3):773-796.
    This article suggests a fresh look at gauge symmetries, with the aim of drawing a clear line between the a priori theoretical considerations involved, and some methodological and empirical non-deductive aspects that are often overlooked. The gauge argument is primarily based on a general symmetry principle expressing the idea that a change of mathematical representation should not change the form of the dynamical law. In addition, the ampliative part of the argument is based on the introduction of new degrees of (...)

    Gauge Symmetries, Symmetry Breaking, and Gauge-Invariant Approaches.Philipp Berghofer, Jordan Francois, Simon Friederich, Henrique Gomes, Guy Hetzroni, Axel Maas & René Sondenheimer - unknown
    Gauge symmetries play a central role, both in the mathematical foundations as well as the conceptual construction of modern (particle) physics theories. However, it is yet unclear whether they form a necessary component of theories, or whether they can be eliminated. It is also unclear whether they are merely an auxiliary tool to simplify (and possibly localize) calculations or whether they contain independent information. Therefore their status, both in physics and philosophy of physics, remains to be fully clarified. In this (...)

    Mathematical Analogies in Physics: The Curious Case of Gauge Symmetries.Guy Hetzroni & Noah Stemeroff - forthcoming - In Carl Posy & Yemima Ben-Menahem (eds.), Mathematical Knowledge, Objects and Applications. Springer.
    Gauge symmetries provide one of the most puzzling examples of the applicability of mathematics in physics. The presented work focuses on the role of analogical reasoning in the gauge argument, motivated by Mark Steiner's claim that the application of the gauge principle relies on a Pythagorean analogy whose success undermines naturalist philosophy. In this paper, we present two different views concerning the analogy between gravity, electromagnetism, and nuclear interactions, each providing a different philosophical response to the problem of the applicability (...)

    Measurements, Preparations, and Interpretations in Quantum Theory: A Comment on Meehan.Guy Hetzroni - forthcoming - British Journal for the Philosophy of Science.
    I address the recent debate between Meehan and Vaidman concerning the claim made by the former for a new problem to quantum mechanics. I argue that while Meehan's incompatibility claim does hold in the situation he presents, it does not genuinely involve considerations that can limit quantum state preparation, nor does it introduce new constrains over possible interpretations of quantum theory.

  5. Protective Measurement and the PBR Theorem.Guy Hetzroni - 2014 - In Shan Gao (ed.), Protective Measurement and Quantum Reality: Towards a New Understanding of Quantum Mechanics. Cambridge, UK: Cambridge University Press.
    Protective measurements illustrate how Yakir Aharonov's fundamental insights into quantum theory yield new experimental paradigms that allow us to test quantum mechanics in ways that were not possible before. As for quantum theory itself, protective measurements demonstrate that a quantum state describes a single system, not only an ensemble of systems, and reveal a rich ontology in the quantum state of a single system. We discuss in what sense protective measurements anticipate the theorem of Pusey, Barrett, and Rudolph (PBR), stating (...)

  6. Physical systems, mathematical representation, and philosophical principles: the EPR paper and its influence.Guy Hetzroni - forthcoming - Iyyun.
    The paper portrays the influence of major philosophical ideas on the 1935 debates on quantum theory that reached their climax in the paper by Einstein, Podosky and Rosen, and describes the relevance of these ideas to the vast impact of the paper. I claim that the focus on realism in many common descriptions of the debate misses important aspects both of Einstein's and Bohr's thinking. I suggest an alternative understanding of Einstein's criticism of quantum mechanics as a manifestation of the (...)

    Relativity and Equivalence in Hilbert Space: A Principle-Theory Approach to the Aharonov–Bohm Effect.Guy Hetzroni - 2020 - Foundations of Physics 50 (2):120-135.
    This paper formulates generalized versions of the general principle of relativity and of the principle of equivalence that can be applied to general abstract spaces. It is shown that when the principles are applied to the Hilbert space of a quantum particle, its law of coupling to electromagnetic fields is obtained. It is suggested to understand the Aharonov-Bohm effect in light of these principles, and the implications for some related foundational controversies are discussed.
