arXiv:2601.04636v1 Announce Type: new Abstract: Nonlocality can be studied through different approaches, such as Bell’s inequalities, and it can be found in numerous quantum states, including GHZ states or graph states. Hardy’s paradox, or Hardy-type nonlocality, provides a way to investigate nonlocality for entangled states of particles without using inequalities. Previous studies of Hardy’s nonl

arXiv:2601.04604v1 Announce Type: new Abstract: The path integral Lindblad dynamics (PILD) method [A. Bose, J. Phys. Chem. Lett. 15(12), 3363-3368 (2024)] had been introduced as a way of incorporating the impact of certain empirical processes like pumps and drains on the dynamics of quantum systems interacting with thermal environments. The method being based on the time-translational invariance o

arXiv:2511.06018v3 Announce Type: replace Abstract: It would be reasonable to recall some critical issues in physical cosmology development. GR was created by A. Einstein in 1915. In 1917 Einstein proposed the first (static) cosmological model. Soon after the A. Eddington proved that the model is unstable therefore it can not be realizable in nature. In 1922 and 1924 A. A. Friedmann found non-stat

arXiv:2512.22965v1 Announce Type: cross Abstract: In a recent preprint [1] Jeffrey Bub presents a discussion of neo-Bohrian interpretations of quantum mechanics, and also of von Neumann’s work on infinite tensor products [2]. He rightfully writes that this work provides a theoretical framework that deflates the measurement problem and justifies Bohr’s insistence on the primacy of classical concept

arXiv:2512.23105v1 Announce Type: new Abstract: What happens to a unified conscious field when its physical implementation straddles a black hole event horizon? This paper addresses that question for integration-based theories, including Integrated Information Theory, Global Workspace Theory, and Predictive Processing. These views share a structural commitment: unity requires a single strongly con

arXiv:2512.22618v1 Announce Type: new Abstract: Since its inception, quantum theory has been the subject of fierce interpretive controversy, which persists to this day. Disputed topics include the basic ontology and dynamics of the theory, the role (if any) of measurement, the meaning of probability, and the issue of non-locality. But there is yet another problem that has been largely ignored: how
Determinism and Indeterminism as Model Artefacts: Toward a Model-Invariant Ontology of Physics

arXiv:2512.22540v1 Announce Type: new Abstract: This paper argues that the traditional opposition between determinism and indeterminism in physics is representational rather than ontological. Deterministic-stochastic dualities are available in principle, and arise in a non-contrived way in many scientifically important models. When dynamical systems admit mathematically equivalent deterministic an

arXiv:2512.24198v1 Announce Type: cross Abstract: This note is a friendly technical check of Jeffrey Bub’s There is No Quantum World (arXiv:2512.18400v2). I flag one unambiguous mathematical slip (a cardinality identity that implicitly assumes the Continuum Hypothesis) and then point out a few places where the discussion of infinite tensor products, “sectorization,” and measurement updates would

arXiv:2512.23923v1 Announce Type: cross Abstract: We apply De Haro’s Geometric View of Theories to one of the simplest quantum systems: a spinless particle on a line and on a circle. The classical phase space M = T*Q is taken as the base of a trivial Hilbert bundle E ~ M x H, and the familiar position and momentum representations are realised as different global trivialisations of this bundle.

arXiv:2512.25057v1 Announce Type: new Abstract: We formalise the self referential definition of physical laws using monotone operators on a lattice of theories, resolving the pathologies of naive set theoretic formulations. By invoking Tarski fixed point theorem, we identify physical theories as least fixed points of admissibility constraints derived from Galois connections. We demonstrate that QE

First, we spell out what she means by interpretation”: an attempt to provide understanding (not just predictions), which may be representationalist or non-representationalist, and which she contrasts with deeper \emph{reductive} (inter-theoretic) e

arXiv:2601.02419v1 Announce Type: cross Abstract: This philosophical dialogue explores the idea that the foundational principles of quantum mechanics need not be interpreted as describing a new physics, but may instead arise from the logical necessity of formalising the act of measurement within a coherent algebraic framework. By pushing this perspective to its extreme, the dialogue argues that th

arXiv:2601.03567v1 Announce Type: cross Abstract: We show that Weyl’s abandoned idea of local scale invariance has a natural realization at the quantum level in pilot-wave (deBroglie-Bohm) theory. We obtain the Weyl covariant derivative by complexifying the electromagnetic gauge coupling parameter. The resultant non-hermiticity has a natural interpretation in terms of local scale invariance of the

We show that the eigenfunctions $\psi_n{=}z^n$ of the quantum Hamiltonian in the complex Bargmann-Fock-Segal representation with $z\in\mathbb C$ are the coordinates of a classical oscillator with energy $E_n=\hbar\omega n$, $n=0,1,2,…\,$.
