The heuristic function of duality 上午8:00 | Latest Results for Synthese Abstract I conceptualise the role of dualities in quantum gravity, in terms of their functions for theory construction. I distinguish between two functions of duality in physical practice: namely, discovering and describing ‘equivalent physics’, versus suggesting ‘new physics’. I dub these the ‘theoretical’ versus the ‘heuristic’ functions of dualities. The distinction… Read more →

Role of Quantum Optics in Synthesizing Quantum Mechanics and Relativity. (arXiv:1911.01642v2 [quant-ph] UPDATED) 上午9:43 | physics.hist-ph updates on arXiv.org Authors: Y. S. Kim Two-photon states produce enough symmetry needed for Dirac’s construction of the two-oscillator system which produces the Lie algebra for the O(3,2) space-time symmetry. This O(3,2) group can be contracted to the inhomogeneous Lorentz group which, according to Dirac,… Read more →

Einstein’s Third Postulate. (arXiv:1506.09070v2 [physics.hist-ph] UPDATED) 2019年11月1日 星期五 下午4:01 | physics.hist-ph updates on arXiv.org Authors: Wolfgang Engelhardt Einstein’s own demonstration of time dilation taken from his book with L. Infeld (1938) is analyzed. His ingenious circumnavigation of an apparent discrepancy between clock synchronisation and Lorentz transformation is discussed.

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 →
