The Born rule. (arXiv:1905.03332v1 [quant-ph])  quant-ph updates on arXiv.org on 2019-5-11 1:18am GMT Authors: Yurii V. Brezhnev We deduce the Born rule. No use is required of quantum postulates. One exploits only rudimentary quantum mathematics — a linear, not Hilbert’s, vector space — and empirical notion of the statistical length of a state. Its statistical nature comes from experimental micro-events: the… Read more →

An experimental Scheme for Gravitational Scattering in Microscale: The effect of spatial superposition of mass on the microstructure of space-time. (arXiv:1905.00484v1 [quant-ph])  quant-ph updates on arXiv.org on 2019-5-04 10:15am GMT Authors: Sahar Sahebdivan In this paper, we are exploring the feasibility of observing non-classical features of gravity in a low-energy regime in a quantum optomechanical experiment. If gravity is to have… Read more →

A minisuperspace model of compact phase space gravity. (arXiv:1904.11338v1 [gr-qc])  hep-th updates on arXiv.org on 2019-4-27 12:44am GMT Authors: Danilo Artigas Guimarey, Jakub Mielczarek, Carlo Rovelli The kinematical phase space of classical gravitational field is flat (affine) and unbounded. Because of this, field variables may tend to infinity leading to appearance of singularities, which plague Einstein’s theory of gravity. The purpose of this… Read more →

A new kind of cyclic universe. (arXiv:1904.08022v1 [gr-qc] CROSS LISTED)  hep-th updates on arXiv.org on 2019-4-20 12:59am GMT Authors: Anna Ijjas, Paul J. Steinhardt Combining intervals of ekpyrotic (ultra-slow) contraction with a (non-singular) classical bounce naturally leads to a novel cyclic theory of the universe in which the Hubble parameter, energy density and temperature oscillate periodically, but the scale factor grows by… Read more →

Searching for quantum black hole structure with the Event Horizon Telescope. (arXiv:1904.05287v1 [gr-qc] CROSS LISTED)  hep-th updates on arXiv.org on 2019-4-13 1:28am GMT Authors: Steven B. Giddings The impressive images from the Event Horizon Telescope sharpen the conflict between our observations of gravitational phenomena and the principles of quantum mechanics. Two related scenarios for reconciling quantum mechanics with the existence 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 →

The Wigner function in the relativistic quantum mechanics. (arXiv:1903.08975v1 [quant-ph])  hep-th updates on arXiv.org on 2019-3-23 1:09am GMT Authors: K. Kowalski, J. Rembielinski A detailed study is presented of the relativistic Wigner function for a quantum spinless particle evolving in time according to the Salpeter equation. A Quantum Mechanics Picture.

Macroscopicity of quantum mechanical superposition tests via hypothesis falsification. (arXiv:1902.11092v1 [quant-ph])  quant-ph updates on arXiv.org on 2019-3-02 12:26am GMT Authors: Björn Schrinski, Stefan Nimmrichter, Benjamin A. 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 →
