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….

Test of the essential collapse-locality loophole IJQF Weekly Papers • quant-ph updates on arXiv.org / 2h arXiv:2603.24909v1 Announce Type: new Abstract: Collapse-locality is an untested loophole in the violation of Bell’s inequalities. The core of the argument is that the time value of photon detection is delayed by the time Tc required by the collapse of its quantum state. The value of… Read more →

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 →

A First-Principles Thermodynamic Uncertainty Relation for Shortcuts to Adiabaticity IJQF Weekly Papers • quant-ph updates on arXiv.org / 1h arXiv:2603.11236v1 Announce Type: new Abstract: We study the fundamental limitations of implementing time-dependent Hamiltonian protocols when ”time” is provided by a quantum clock rather than an external classical parameter. For a parametric harmonic oscillator controlled through a shortcut-to-adiabaticity (STA) schedule and coupled to… Read more →
