Expectation-Realization Interpretation of Quantum Superposition

quant-ph updates on arXiv.org / 10h

arXiv:2511.04154v1 Announce Type: new Abstract: By comparing Schr\”odinger’s cat with its classical counterpart, I show that a quantum superposition should be understood as an expectation over possible eigenstates weighted by wavelike probabilities. Upon the occurrence of a certain event, the quantum system is randomly realized into one of the possible eigenstates due to its intrinsic stochastici

Determinism and Asymmetry in General Relativity

arXiv:2503.05668v2 Announce Type: replace Abstract: This paper concerns the question of which collections of general relativistic spacetimes are deterministic relative to which definitions. We begin by considering a series of three definitions of increasing strength due to Belot (1995). The strongest of these definitions is particularly interesting for spacetime theories because it involves an asy

Where Photons Have Been: Nowhere Without All Components of Their Wavefunctions

arXiv:2507.06362v2 Announce Type: replace-cross Abstract: A nested interferometer experiment by Danan et al (2013) is discussed and some claims evaluated concerning the whereabouts of the photon, primarily in the context of time-symmetric interpretations of quantum theory including the Two-State Vector Formalism (TSVF) and the Transactional Interpretation (TI). It is pointed out that the TSVF acco

The Newtonian limit of orthonormal frames in metric theories of gravity

arXiv:2410.01800v5 Announce Type: replace-cross Abstract: We extend well-known results on the Newtonian limit of Lorentzian metrics to orthonormal frames. Concretely, we prove that, given a one-parameter family of Lorentzian metrics that in the Newtonian limit converges to a Galilei structure, any family of orthonormal frames for these metrics converges pointwise to a Galilei frame, assuming that

EPR Revisited: Context-Indexed Elements of Reality and Operational Completeness

IJQF Weekly Papers

physics.hist-ph updates on arXiv.org / 1d

arXiv:2511.01930v2 Announce Type: replace-cross Abstract: We reframe the EPR argument through an operational lens, replacing the notion of fixed “elements of reality” with context-indexed conditional states – what’s often referred to as a measurement assemblage. This move deliberately sidesteps the assumption of context-independent values for incompatible observables. Our updated version of the Re

Legal Entanglement

arXiv:2511.03982v1 Announce Type: cross Abstract: Quantum entanglement is a phenomenon in which two physical systems are correlated in such a way that they appear to instantaneously affect one another, regardless of the distance between them. As commonly understood, Bell’s Theorem famously demonstrates that any causal explanation of entanglement must discard either locality (the principle that not

Resolution of Loschmidts Paradox via Geometric Constraints on Information Accessibility

arXiv:2511.03843v1 Announce Type: cross Abstract: We resolve Loschmidt’s paradox — the apparent contradiction between time-reversible microscopic dynamics and irreversible macroscopic evolution — including the long-standing puzzle of the thermodynamic arrow of time. The resolution: entropy increases not because dynamics are asymmetric, but because information accessibility is geometrically bound
