Experimental evidence for the Unruh effect. (arXiv:1903.00043v3 [gr-qc] UPDATED) 2019年10月18日 星期五 下午7:34 | gr-qc updates on arXiv.org Authors: Morgan H. Lynch, Eliahu Cohen, Yaron Hadad, Ido Kaminer We examine the radiation emitted by high energy positrons channeled into silicon crystal samples. The positrons are modeled as semiclassical vector currents coupled to an Unruh-DeWitt detector to incorporate any local change in the energy of the… 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 →

An Entropic Dynamics Approach to Geometrodynamics. (arXiv:1910.01188v1 [gr-qc]) 下午12:34 | quant-ph updates on arXiv.org Authors: Selman Ipek, Ariel Caticha In the Entropic Dynamics (ED) framework quantum theory is derived as an application of entropic methods of inference. The physics is introduced through appropriate choices of variables and of constraints that codify the relevant physical information. In previous work, a manifestly covariant ED… Read more →

Generalised Reichenbachian common cause systems 上午8:00 | Latest Results for Synthese Abstract The principle of the common cause claims that if an improbable coincidence has occurred, there must exist a common cause. This is generally taken to mean that positive correlations between non-causally related events should disappear when conditioning on the action of some underlying common cause. The extended interpretation… Read more →
