Bohm’s approach to quantum mechanics: Alternative theory or practical picture?. (arXiv:1707.00609v2 [quant-ph] UPDATED)  physics.hist-ph updates on arXiv.org on 2018-10-06 12:59am GMT Authors: A. S. Sanz Since its inception Bohmian mechanics has been generally regarded as a hidden-variable theory aimed at providing an objective description of quantum phenomena. To date, this rather narrow conception of Bohm’s proposal has caused it more rejection… Read more →

A Toy Model of the Information Paradox in Empty Space. (arXiv:1809.10154v1 [hep-th])  gr-qc updates on arXiv.org on 2018-9-28 12:43pm GMT Authors: Suvrat Raju A sharp version of the information paradox involves a seeming violation of the monogamy of entanglement during black hole evaporation. We construct an analogous paradox in empty anti-de Sitter space. In a local quantum field theory, Bell correlations… Read more →

Bouncing oil droplets, de Broglie’s quantum thermostat and convergence to equilibrium. (arXiv:1807.00569v4 [quant-ph] UPDATED)  quant-ph updates on arXiv.org on 2018-9-22 7:24am GMT Authors: Mohamed Hatifi, Ralph Willox, Samuel Colin, Thomas Durt Recently, the properties of bouncing oil droplets, also known as “walkers”, have attracted much attention because they are thought to offer a gateway to a better understanding of quantum behaviour. They constitute indeed… Read more →

Dimensional reduction via a novel Higgs mechanism. (arXiv:1806.07520v1 [gr-qc] CROSS LISTED)  hep-th updates on arXiv.org on 2018-6-23 1:03am GMT Authors: Saurya Das, Mir Faizal Many theories of quantum gravity live in higher dimensions, and their reduction to four dimensions via mechanisms such as Kaluza-Klein compactification or brane world models have associated problems. We propose a novel mechanism of dimensional reduction via spontaneous… Read more →

Quantum gravity tomography. (arXiv:1806.05643v1 [hep-th])  hep-th updates on arXiv.org on 2018-6-16 1:14am GMT Authors: William Donnelly The holographic principle posits that all quantum information in a region of spacetime is encoded on its boundary. While there is strong evidence for this principle in certain models of quantum gravity in asymptotically anti-de Sitter spacetime, it is yet to be established whether holography… Read more →

Weekly Papers on Quantum Foundations (23)

Why initial system-environment correlations do not imply the failure of complete positivity: a causal perspective. (arXiv:1806.02381v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-6-09 12:56am GMT Authors: David Schmid, Katja Reid, Robert W. Spekkens The common wisdom in the field of quantum information theory is that when a system is initially correlated with its environment, the map describing its evolution may fail to be… Read more →

Continuity of measurement outcomes. (arXiv:1805.12404v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-6-02 3:59am GMT Authors: J. Sperling It is demonstrated that the collapse of the wave function is equivalent to the continuity of measurement outcomes. The latter states that a second measurement has to result in the same outcome as the first measurement of the same observable for a vanishing time… Read more →

Lets Talk About Black Hole Singularities. (arXiv:1805.05865v2 [physics.pop-ph] CROSS LISTED)  hep-th updates on arXiv.org on 2018-5-19 12:49am GMT Authors: Abraham Loeb (Harvard) Does the collision of black hole singularities imprint an observable quantum signature on the resulting gravitational wave signal? Stephen Hawking: To Understand the Universe. (arXiv:1803.09197v2 [physics.hist-ph] UPDATED)  hep-th updates on arXiv.org on 2018-5-19 12:49am GMT Authors: James B. Hartle (UCSB and SFI)… Read more →

A theorem about time evolution in the quantum mechanics. (arXiv:1805.03689v1 [quant-ph])  hep-th updates on arXiv.org on 2018-5-11 3:26am GMT Authors: M. A. Rajabpour Under broad conditions, we prove that the probability amplitudes in the quantum mechanics are either always constant in time or changing continuously in any interval of time. Testing Lorentz- and CPT-invariance with ultracold neutrons. (arXiv:1805.04062v1 [hep-th])  hep-th updates… Read more →
