Causal Trade-Offs in Superluminal Extensions of Relativity. A no-go theorem IJQF Weekly Papers • quant-ph updates on arXiv.org / 1d arXiv:2610.00494v1 Announce Type: new Abstract: Extensions of relativity that include superluminal reference frames have recently been proposed by Dragan and Ekert as a way to reconcile relativistic symmetry with quantum uncertainty. In this work, we develop a causal modelling framework… Read more →

The Uncertainty Principle, Uncertainty Relations, and Underlying Trajectories: Feynman, Nelson, Bohm, and Persistent Kac-Dirac Dynamics IJQF Weekly Papers • quant-ph updates on arXiv.org / 1d arXiv:2609.29248v1 Announce Type: new Abstract: A distinction should be made between quantum uncertainty relations and the broader uncertainty principle. The former are precise statistical consequences of quantum mechanics; the latter, when interpreted as excluding simultaneously… Read more →
