The De Broglie-Bohm Theory As A Rational Completion Of Quantum Mechanics

We try to give a physical meaning to the wave function or quantum state of a system, apart from being a very efficient tool for predicting results of measurements on that system. In other words, we ask: what does it mean for a system outside the laboratories to have a wave function? We first explain why two possible, and probably common, answers to... Read more →

Analysis of Everett’s quantum interpretation from the point of view of a Bohmian

Aurelien Drezet (CNRS-University Joseph Fourier) In this article we discuss and compare the many worlds interpretation (MWI) proposed by Everett and others and the pilot wave interpretation (PWI) of de Broglie and Bohm. We focus our study on two fundamental issues: i) the ontological framework definition, and ii) the meaning of probability (i.e., the Born rule). We show that PWI... Read more →

Reply to a Comment on "Role of Potentials in the Aharonov-Bohm Effect"

Lev Vaidman Preceding Comment challenged my claim that potentials might be just auxiliary mathematical tools and that they are not necessary for explaining physical phenomena. The Comment did not confront my explanation without potentials of the Aharonov-Bohm effects appeared in the original paper, but stated that I cannot apply this explanation for seven other examples. In my reply I provide... Read more →

Comment on “Role of potentials in the Aharonov-Bohm effect”

Yakir Aharonov, Eliahu Cohen, and Daniel Rohrlich Are the electromagnetic scalar and vector potentials dispensable? Vaidman [Phys. Rev. A 86, 040101(R) (2012)] has suggested that local interactions of gauge-invariant quantities, e.g., magnetic torques, suffice for the description of all quantum electromagnetic phenomena. We analyze six thought experiments that challenge this suggestion. All of them have explanations in terms of local interactions of gauge-dependent quantities, and,... Read more →

Bell on Bohm

Sheldon Goldstein Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” A memorial conference for John Bell, open to the public, was held at Rutgers University around 20 years ago. I gave there a short talk on Bell's views about David Bohm's ``hidden variables'' formulation of quantum mechanics, a version of quantum mechanics often called the de... Read more →

The PBR theorem seen from the eyes of a Bohmian

The aim of this paper is to present an analysis of the new theorem by Pusey, Barrett and Rudolph (PBR) concerning ontic and epistemic hidden variables in quantum mechanics [Nature Phys. 8, 476 (2012)]. This is a kind of review and defense of my previous critical analysis done in the context of Bohmian mechanics. This is also the occasion for me to review some of... Read more →

Weekly Papers on Quantum Foundations (25)

Fixing extensions to General Relativity in the non-linear regime. (arXiv:1706.07421v1 [gr-qc])  hep-th updates on arXiv.org on 2017-6-24 7:39am GMT Authors: Juan Cayuso, Néstor Ortiz, Luis Lehner The question of what gravitational theory could supersede General Relativity has been central in theoretical physics for decades. Many disparate alternatives have been proposed motivated by cosmology, quantum gravity and phenomenological angles, and have been subjected to... Read more →
