Realism and causality I: Pilot wave and retrocausal models as possible facilitators

Eliahu Cohen, Marina Cortês, Avshalom C. Elitzur, Lee Smolin (Submitted on 13 Feb 2019 (v1), last revised 19 Mar 2019 (this version, v2)) https://arxiv.org/abs/1902.05108v2 Of all basic principles of classical physics, realism should arguably be the last to be given up when seeking a better interpretation of quantum mechanics. We examine the de Broglie-Bohm pilot wave theory as a well developed example of… Read more →

Less is More: Born’s Rule from Quantum Frequentism. (arXiv:1903.12027v1 [quant-ph])  quant-ph updates on arXiv.org on 2019-3-30 1:40am GMT Authors: Lionel Brits Accounting for Born’s rule from first principles remains an open problem among the foundational issues in quantum mechanics. Proponents of the many-worlds interpretation have argued that histories that violate Born’s rule have vanishing norms, and so are unphysical. This argument… Read more →

Stickler, Klaus Hornberger We establish an objective scheme to determine the macroscopicity of quantum mechanical superposition tests, which is based on the Bayesian hypothesis falsification of macrorealistic modifications of quantum theory. The measure uses the raw data gathered… Read more →

Outline for a quantum theory of gravity. (arXiv:1901.05953v1 [gr-qc])  hep-th updates on arXiv.org on 2019-1-19 7:38am GMT Authors: Tejinder P. Singh By invoking an asymmetric metric tensor, and borrowing ideas from non-commutative geometry, string theory, and trace dynamics, we propose an action function for quantum gravity. The action is proportional to the four dimensional non-commutative curvature scalar (which is torsion dependent)… Read more →
