A new perspective on CP and T violation

Abhay Ashtekar

Published Jul 4, 2013• 1 citation

Abstract

It is shown that the results of CP and T violation experiments can be interpreted using a very general framework that does not require a Hilbert space of states or linear operators to represent the symmetries or dynamics. Analysis within this general framework brings out the aspects of quantum mechanics that are essential for this interpretation. More importantly, should quantum mechanics be eventually replaced by a new paradigm, this framework could \emph{still} be used to establish violation of CP and T invariance from the already known experimental results. This work arose as a `formal response' to a talk "Three Merry Roads to T-Violation" by Dr. Bryan Roberts [1]. Both talks were given at a "Workshop on Cosmology and Time" held at Penn State in April 2013, which brought together physicists and philosophers of science.

Making better sense of quantum mechanics

N. David Mermin

We still lack any consensus about what one is actually talking about as one uses quantum mechanics. There is a gap between the abstract terms in which the theory is couched and the phenomena the theory enables each of us to account for so well. Because it has no practical consequences for how we each use quantum mechanics to deal with physical problems, this cognitive dissonance has managed to coexist with the quantum theory from the very beginning. The absence of conceptual clarity for almost a century suggests that the problem might lie in some implicit misconceptions about the nature of scientific explanation that are deeply held by virtually all physicists, but are rarely explicitly acknowledged. I describe here such unvoiced but widely shared assumptions. Rejecting them clarifies and unifies a range of obscure remarks about quantum mechanics made almost from the beginning by some of the giants of physics, many of whom are held to be in deep disagreement. This new view of physics requires physicists to think about science in an unfamiliar way. My primary purpose is to explain the new perspective and urge that it be taken seriously. My secondary aims are to explain why this perspective differs significantly from what Bohr, Heisenberg, and Pauli had been saying from the very beginning, and why it is not solipsism, as some have maintained. To emphasize that this is a general view of science, and not just of quantum mechanics, I apply it to a long-standing puzzle in classical physics: the apparent inability of physics to give any meaning to 'Now'-the present moment.

CONFERENCE “TWO DAYS OF HISTORY AND EPISTEMOLOGY OF QUANTUM INTERPRETATIONS”

Alexander A. Pechenkin

On April 17-18, 2023, an international conference dedicated to the problems of history and philosophy of quantum physics was held in Paris, bringing together physicists, philosophers and historians of science from Europe, America and Australia. The conference discussed both the issues put on the agenda by quantum technologies and traditional philosophical issues of quantum mechanics. The conference was associated with the presentation of the book “The Oxford Handbook of Quantum Interpretations” (2022) and most of the speakers were authors of this collective work.

Towards a new interpretation of quantum mechanics?

André Julg, Pierre Julg

Abstract Quantum mechanics is a remarkable formalism for studying problems in the microscopic domain, and nobody has reasonably contested its power. Nevertheless, in spite of the many interpretations which have been proposed, its true meaning is far from being clear. The aim of this preliminary paper is to show that it is possible to conceive within a classical framework an interpretation of quantum mechanics and to make its limits of validity precise.

A Novel Way of `Understanding' Quantum Mechanics

Armin Nikkhah Shirazi

Written at a level appropriate for an educated lay audience, this paper attempts to give a primarily conceptual overview of a framework recently introduced in reference [3] by this author, which attempts to clarify what quantum mechanics tells us about reality. Physicists may find this pa-per useful because it focuses on the central ideas of the framework at a conceptual level, thereby lessening their unfamiliarity, an unavoidable fea-ture of truly novel ideas. The author hopes that this article will motivate physicists to seriously evaluate the mathematical details of the framework given in the original reference...I think I can safely say that nobody understands Quantum Mechanics.”[1]

3-body, classical–quantum, discrete–continuous

Thierry Paul

This special issue of Mathematical Structures in Computer Science contains several contributions to the Workshop 3 corps, classique-quantique, discret-continu. The Workshop was held at the Ecole Normale Supérieure, Paris on 28–29 September 2004 in the framework of the Collectif Histoire Philosophie Sciences. The Workshop was organised by Giuseppe Longo and Thierry Paul with the aim of bringing together mathematicians, physicists, computer scientists and philosophers.

CP Violation and Quantum Mechanics in the B System

Boris J. Kayser

We discuss the testing of the Standard Model of CP violation, and the search for CP-violating effects from beyond the Standard Model, in $B$ decays. We then focus on the quantum mechanics of the experiments on CP violation to be performed at $B$ factories. These experiments will involve very pretty Einstein-Podolsky-Rosen correlations. We show that the physics of these experiments can be understood without invoking the ``collapse of the wave function," and without the mysteries that sometimes accompany discussions of EPR effects.
