A preference for Dynamical Dark Energy?. (arXiv:2107.14129v1 [astro-ph.CO]) 上午9:55 | gr-qc updates on arXiv.org Authors: David Benisty, Denitsa Staicova Dynamical Dark Energy (DDE) is a possible solution to the Hubble tension. This work analyses the combination of Baryon Acoustic Oscillation (BAO) data that include $19$ points from the range $0.11 \le z \le 2.40$ and additional points from the Cosmic Microwave Background… Read more →
The hydrogen atom: consideration of the electron self-field. (arXiv:2101.02202v1 [quant-ph]) 上午9:31 | Leon V. Biguaa, Vladimir V. Kassandrov | quant-ph updates on arXiv.org We substantiate the need for account of the proper electromagnetic field of the electron in the canonical problem of hydrogen in relativistic quantum mechanics. From mathematical viewpoint, the goal is equivalent to determination of the spectrum of… Read more →

Vacuum entanglement harvesting with a zero mode. (arXiv:2002.11790v1 [quant-ph]) 下午12:05 | Erickson Tjoa, Eduardo Martín-Martínez | quant-ph updates on arXiv.org We investigate vacuum entanglement harvesting in the presence of a zero mode. We show that, for a variety of detector models and couplings (namely, Unruh-DeWitt qubit and harmonic oscillator detectors, amplitude and derivative coupling), the results are strongly dependent on… Read more →
Joseph Polchinski: A Biographical Memoir. (arXiv:2002.02371v1 [physics.hist-ph]) 上午9:47 | physics.hist-ph updates on arXiv.org Authors: Raphael Bousso, Fernando Quevedo, Steven Weinberg Joseph Polchinski (1954-2018), one of the the leading theoretical physicists of the past 50 years, was an exceptionally broad and deep thinker. He made fundamental contributions to quantum field theory, advancing the role of the renormalization group, and to cosmology, addressing the cosmological… Read more →
MOND vs. dark matter in light of historical parallels. (arXiv:1910.04368v1 [astro-ph.GA]) 2019年10月11日 星期五 下午8:32 | physics.hist-ph updates on arXiv.org Authors: Mordehai Milgrom MOND is a paradigm that contends to account for the mass discrepancies in the Universe without invoking `dark’ components, such as `dark matter’ and `dark energy’. It does so by supplanting Newtonian dynamics and General Relativity, departing from them… 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 →
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 →
