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 →

To be unitary-invariant or not?: a simple but non-trivial proposal for the complexity between states in quantum mechanics/field theory. (arXiv:1906.02063v2 [hep-th] UPDATED)  hep-th updates on arXiv.org on 2019-6-14 1:10pm GMT Authors: Run-Qiu Yang, Yu-Sen An, Chao Niu, Cheng-Yong Zhang, Keun-Young Kim We make comments on some shortcomings of the non-unitary-invariant and non-bi-invariant complexity in quantum mechanics/field theory and argue that the unitary-invariant and bi-invariant complexity… 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 →

Exploring strong-field deviations from general relativity via gravitational waves. (arXiv:1904.04258v2 [gr-qc] CROSS LISTED)  hep-th updates on arXiv.org on 2019-6-01 12:22am GMT Authors: Steven B. Giddings, Seth Koren, Gabriel Treviño Two new observational windows have been opened to strong gravitational physics: gravitational waves, and very long baseline interferometry. This suggests observational searches for new phenomena in this regime, and in particular for those necessary… 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 →

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 →
