What did Bell really prove?

Jean Bricmont Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” The goal of this paper is to give a pedagogical introduction to Bell's theorem and its implication for our view of the physical world, in particular how it establishes the existence of non local effects or of actions at a distance. We also discuss several misunderstandings... Read more →

Submitted paper: Haag’s Theorem as a Reason to Reconsider Direct-Action Theories

ABSTRACT. It is argued that the severe consequences of Haag’s inconsistency theorem for quantum field theories can be successfully evaded in the direct-action approach. Some recent favorable comments of John Wheeler, often mistakenly presumed to have abandoned his own (and Feynman’s) direct-action theory, together with the remarkable immunity of direct-action quantum electrodynamics to Haag’s theorem, suggest that it may well...

Local Causality, Probability and Explanation

Richard A. Healey Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” In papers published in the 25 years following his famous 1964 proof John Bell refined and reformulated his views on locality and causality. Although his formulations of local causality were in terms of probability, he had little to say about that notion. But assumptions about probability are implicit in... Read more →

John Stuart Bell: recollections of a great scientist and a great man

John Stuart Bell: recollections of a great scientist and a great man

This contribution to the book in honour of J.S. Bell will probably differ from the remaining ones, in particular since only a part of it will be devoted to specific technical arguments. In fact I have considered appropriate to share with the community of physicists interested in the foundational problems of our best theory the repeated interactions I had with... Read more →
