Knowledge of the Quantum Domain: an Overlap Strategy (2022)
Journal Article
Fraser, J. D., & Vickers, P. (2022). Knowledge of the Quantum Domain: an Overlap Strategy. The British Journal for the Philosophy of Science, https://doi.org/10.1086/721635

The existence of multiple interpretations of quantum mechanics appears to pose a serious challenge for knowledge claims about the quantum domain. Hoefer (2020) argues that a scientific realist epistemology must be abandoned in this context, while Cal... Read More about Knowledge of the Quantum Domain: an Overlap Strategy.

Taking approximations seriously: The cases of the Chew and Nambu-Jona-Lasinio models (2022)

The twin origins of renormalization group concepts (2021)
Journal Article
Fraser, J. D. (2021). The twin origins of renormalization group concepts. Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 89, 114-128. https://doi.org/10.1016/j.shpsa.2021.08.002

This paper traces the origin of renormalization group concepts back to two strands of 1950s high energy physics: the causal perturbation theory programme, which gave rise to the Stueckelberg-Petermann renormalization group, and the debate about the c...

Renormalization and the Formulation of Scientific Realism (2018)
Journal Article
Fraser, J. D. (2018). Renormalization and the Formulation of Scientific Realism. Philosophy of Science, 85(5), 1164-1175. https://doi.org/10.1086/699722

Providing a precise statement of their position has long been a central challenge facing scientific realists. This article draws some morals about how realism ought to be formulated from the renormalization group framework in high-energy physics.

The Real Problem with Perturbative Quantum Field Theory (2018)
Journal Article
Fraser, J. D. (2020). The Real Problem with Perturbative Quantum Field Theory. The British Journal for the Philosophy of Science, 71(2), 391-413. https://doi.org/10.1093/bjps/axx042

The perturbative approach to quantum field theory (QFT) has long been viewed with suspicion by philosophers of science. This article offers a diagnosis of its conceptual problems. Drawing on Norton’s ([2012]) discussion of the notion of approximation... Read More about The Real Problem with Perturbative Quantum Field Theory.
