Conventionalism in general relativity?: formal existence proofs and Reichenbach’s theorem {\theta} in context IJQF Weekly Papers • physics.hist-ph updates on arXiv.org / 7d arXiv:2603.24608v1 Announce Type: new Abstract: Weatherall and Manchak (2014) show that, under reasonable assumptions, Reichenbachean universal effects, constrained to a rank-2 tensor field representation in the geodesic equation, always exist in non-relativistic gravity but not so for relativistic spacetimes….

Bell-EPR Correlations within Local Quantum Theory IJQF Weekly Papers • quant-ph updates on arXiv.org / 2h arXiv:2603.18198v1 Announce Type: new Abstract: We present a local unitary theory of a Bell-EPR measurement, starting with the premeasurement filtering of the individual photon polarizations and extending through the detection process involving four photodetectors, two at each receiving station. The essential feature is that decoherence occurs… Read more →

Universal Growth of Krylov Complexity Across A Quantum Phase Transition IJQF Weekly Papers • quant-ph updates on arXiv.org / 11h arXiv:2510.13947v1 Announce Type: new Abstract: We study the statistical properties of the spread complexity in the Krylov space of quantum systems driven across a quantum phase transition. Using the diabatic Magnus expansion, we map the evolution to an effective one-dimensional hopping model…. Read more →

Yair Mulian For almost 75 years, the general solution for the Schrödinger equation was assumed to be generated by a time-ordered exponential known as the Dyson series. We discuss under which conditions the unitarity of this solution is broken, and additional singular dynamics emerges. Then, we provide an alternative construction that is manifestly unitary, regardless of the choice of the… Read more →

The cosmological frame principle and cosmic acceleration. (arXiv:2304.12733v1 [gr-qc])   from  gr-qc updates on arXiv.org  by  Spiros Cotsakis, Jose P. Mimoso, John Miritzis Wed Apr 26 2023 08:57:12 (2 days) # 7. We discuss cosmological implications of the frame principle which states that physics is independent of frames. We show that there are frame-independent solutions that are globally stable, suggesting… Read more →
