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 →

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 →

Unwinding Short-Range Entanglement. (arXiv:1804.11236v1 [quant-ph] CROSS LISTED)  hep-th updates on arXiv.org on 2018-5-05 1:16am GMT Authors: Abhishodh Prakash, Juven Wang, Tzu-Chieh Wei Symmetry-Protected Topological (SPT) phases are short-range entangled (SRE) gapped phases of quantum matter protected by global symmetries, that cannot be unitarily and adiabatically deformed to a trivial phase without closing the gap or breaking symmetry. In this work, we show that,… Read more →

Are there really conformal frames? Uniqueness of affine inflation. (arXiv:1802.01247v2 [gr-qc] UPDATED)  hep-th updates on arXiv.org on 2018-4-28 8:09am GMT Authors: Hemza Azri Here we concisely review the nonminimal coupling dynamics of a single scalar field in the context of purely affine gravity and extend the study to multifield dynamics. The coupling is performed via an affine connection and its associated… Read more →

H-theorem and Maxwell Demon in Quantum Physics. (arXiv:1804.06886v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-4-21 2:11am GMT Authors: N.S. Kirsanov, A.V. Lebedev, I.A. Sadovskyy, M.V. Suslov, V.M. Vinokur, G. Blatter, G.B. Lesovik The Second Law of Thermodynamics states that temporal evolution of an isolated system occurs with non-diminishing entropy. In quantum realm, this holds for energy-isolated systems the evolution of which is described by the so-called unital… Read more →
