## On the Reality of the Wavefunction

Dear All, Recently, I have written a paper arguing against the claim of the PBR theorem. That is, I have shown that statistics of PBR's scenario can be reproduced by $\psi$-epistemic ontological models. However, the only thing that is required is to consider the role of the measurement ontic states. In what follows, I have provided the abstract of the... Read more →

## Quantum mechanics from an epistemic state space

Per Östborn (Lund University, Sweden) We derive the Hilbert space formalism of quantum mechanics from epistemic principles. A key assumption is that a physical theory that relies on entities or distinctions that are unknowable in principle gives rise to wrong predictions. An epistemic formalism is developed, where concepts like individual and collective knowledge are used, and knowledge may be actual... Read more →

## 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 efficient 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 →

## History of Quantum Mechanics or the Comedy of Errors

Jean Bricmont (IRMP, Universite catholique de Louvain) The goal of this paper is to explain how the views of Albert Einstein, John Bell and others, about nonlocality and the conceptual issues raised by quantum mechanics, have been rather systematically misunderstood by the majority of physicists.

## Quantum nonlocality observable on a non-statistical level: idea, experimental evidence, fundamental consequences

Sergey A. Emelyanov (A. F. Ioffe Institute) Today quantum nonlocality is discussed only in the context of EPR situation where we face a macroscopic system which is fundamentally indivisible insofar as it consists of entangled distant particles. But quantum formalism implies a one more type of indivisibility. It is the indivisibility of a quantum state per se regardless of its... Read more →

## Entangled history?

Did anyone read the papers by Wilczek on entangled history? Any comment?

## Response to Wiseman, Rieffel, and Cavalcanti on Bell's 1964 Paper

Edward J. Gillis Wiseman has claimed that Bell was wrong in stating that determinism was inferred rather than assumed in the summary of the EPR argument in his 1964 paper. The reply of Wiseman and his co-authors to my comment misstates my reasons for disputing this point, and fails to address the central criticism that their claim is based on a seriously flawed...

## Quantum Equivalence Principle In A Universal Hilbert Space

Michael York We propose a unifying quantum framework in which Einstein’s equivalence principle is generalized to a universal Hilbert space in which all interaction is treated as a generalization of a frame transformation and represented by a change of basis. In our scheme intrinsic information is carried by a physical system independently of any frame of reference (or basis). A... Read more →

## Emergence of Spacetime Through Interaction

Furkan Semih Dündar and Baris Tamer Tonguc We study kinematics of atoms and molecules in quantum shape dynamics. We analyzed a model universe where there is only electrical force between protons and electrons. A similar model where there is only gravitational attraction between masses was investigated by Barbour, Koslowski and Mercati before. Our results is an expansion of the ideas there. We found...

## Resolving the Problem of Definite Outcomes of Measurements

Art Hobson (University of Arkansas) The entangled "Schrodinger's cat state" of a quantum and its measurement apparatus is not a paradoxical superposition of states but is instead a non-paradoxical superposition of nonlocal coherent correlations between states: An un-decayed nucleus is correlated with a live cat, and a decayed nucleus is correlated with a dead cat. This elucidation of entanglement is demonstrated by quantum-theoretical analysis and... Read more →

## An Information-Based Solution to the Measurement Problem in Quantum Mechanics

Maya Lincoln and Avi Wassery (University of Haifa) One of the most intriguing challenges that physics has been confronting during the recent decades is the measurement problem in quantum mechanics (QM). Despite the extensive research on this enigmatic phenomenon, science is still searching an explanation for the irreversible transformation of a measured system from a wave-like (quantum) state to a deterministic state. To... Read more →
