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… 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 →

Bell non-locality, Hardy’s paradox and hyperplane dependence

Gordon N. Fleming Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” I argue, in section 4, that the ‘elements of reality’ of Hardy’s famous gedanken experiment can retain their Lorentz invariance, i.e., their frame independence, if one recognizes the hyperplane dependence of their localization. This requires avoiding the conflation of hyperplane dependence with frame dependence, which… Read more →

John Bell’s Varying Interpretations of Quantum Mechanics

H. Dieter Zeh Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem”. For the first time I met John Bell at the Varenna conference of 1970 (d’Espagnat, 1971). I had been invited on suggestion by Eugene P. Wigner, who had already helped me to publish my first paper on the concept of what was later called decoherence… Read more →

John Bell – The Irish Connection

Andrew Whitaker (Queen’s University Belfast) Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem”. John Bell lived in Ireland for only 21 years, but throughout his life he remembered his Irish upbringing with fond memories, pride and gratitude. Ireland has a very respectable tradition in physics, and particularly mathematical physics (McCartney and Whitaker 2003). As early as… Read more →

Gravitation and the noise needed in objective reduction models

Stephen L. Adler Institute for Advanced Study, Einstein Drive, Princeton, NJ 08540, USA. Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem”. I briefly recall intersections of my research interests with those of John Bell. I then argue that the noise needed in theories of objective state vector reduction most likely comes from a fluctuating complex part in the… Read more →
