Critical look at the time-energy uncertainty relations. (arXiv:1908.05273v1 [quant-ph]) 上午9:48 | quant-ph updates on arXiv.org Authors: K. Urbanowski The Heisenberg and Mandelstam-Tamm time-energy uncertainty relations are analyzed. The conlusion resulting from this analysis is that within the Quantum Mechanics of Schr\”{o}dinger and von Neumann, the status of these relations can not be considered as the same as the status of the… Read more →

Do the EPR correlations pose a problem for causal decision theory? 上午8:00 | Latest Results for Synthese Abstract We argue that causal decision theory (CDT) is no worse off than evidential decision theory (EDT) in handling entanglement, regardless of one’s preferred interpretation of quantum mechanics. In recent works, Ahmed (Evidence, decision, and causality, Cambridge University Press, Cambridge, 2014) and Ahmed and… Read more →

From probabilistic mechanics to quantum theory. (arXiv:1907.08513v1 [quant-ph]) 下午3:18 | quant-ph updates on arXiv.org Authors: Ulf Klein We show that quantum theory (QT) is a substructure of classical probabilistic physics. The central quantity of the classical theory is Hamilton’s function $H(q,p)$, which determines canonical equations, a corresponding flow $\phi_{t}^{H}$, and a Liouville equation for the probability density $\rho(q,p,t)$. We extend this… Read more →

First Demonstration of Antimatter Quantum Interferometry. (arXiv:1906.08665v1 [quant-ph])  quant-ph updates on arXiv.org on 2019-6-21 2:06am GMT Authors: M. Giammarchi This paper descrives the first experimental evidence of antimatter-wave interference, a process at the heart of Quantum Physics and its interpretation. For the case of ordinary matter particles, interference phenomena have been observed in a variety of cases, ranging to electrons up… Read more →

Quantum Nature of Black Holes: Fast Scrambling versus Echoes. (arXiv:1906.02653v1 [hep-th])  hep-th updates on arXiv.org on 2019-6-07 1:17pm GMT Authors: Krishan Saraswat, Niayesh Afshordi Two seemingly distinct notions regarding black holes have captured the imagination of theoretical physicists over the past decade: First, black holes are conjectured to be fast scramblers of information, a notion that is further supported through connections to… Read more →

A different perspective on the problem of time in quantum gravity. (arXiv:1905.09860v1 [gr-qc])  gr-qc updates on arXiv.org on 2019-5-28 12:29am GMT Authors: Mariano Bauer, Cesar Augusto Aguillon, Gustavo Garcia The perspective is advanced that the time parameter in quantum mechanics corresponds to the time coordinate in a Minkowski flat spacetime local approximation to the actual dynamical curved spacetime of General Relativity, rather than… Read more →
