arXiv:2512.20788v1 Announce Type: new Abstract: We study finite two-dimensional disordered systems with periodic confinement. At low energies, eigenstates exhibit strong Anderson localization, while at higher energies a subset of states forms variational scars with anisotropic intensity patterns that violate random wave expectations. Scaling theory predicts that all states localize in two dimensio
Deriving the Born Rule from a model of the quantum measurement process

arXiv:2408.06375v4 Announce Type: replace-cross Abstract: The quantum mechanics postulate called the Born Rule attributes a probabilistic meaning to a wave function. This paper derives the Born Rule from other quantum principles along with a model of the measurement process. The nondeterministic nature of quantum measurements is hypothesized to arise from an ignorance of the quantum states of a me

physics.hist-ph updates on arXiv.org / 3d
arXiv:2011.12716v5 Announce Type: replace-cross Abstract: The Frauchiger-Renner argument aims to show that `quantum theory cannot consistently describe the use of itself’: in many-party settings where agents are themselves subject to quantum experiments, agents may make predictions that contradict observations. Here, we introduce a simplified setting using only three agents, that is independent of

arXiv:2512.17024v2 Announce Type: replace-cross Abstract: Recent proposals suggest that detecting entanglement between two spatially superposed masses would establish the quantum nature of gravity. However, these gravitationally induced entanglement (GIE) experiments rely on assumptions about subsystem independence. We sharpen the theoretical underpinnings of such proposals by examining them throu

arXiv:2512.09950v2 Announce Type: replace-cross Abstract: What does “Big Bang” actually mean? What was the origin of these two words? It has often been said that the expression “Big Bang” began as an insult. Even if this were true, it would be just an irrelevant part of the whole issue. There are many more aspects hidden under this name, and which are seldom explained. They will be discussed i
Bell Nonlocality as a Covariance Obstruction in Locally Covariant Quantum Field Theory

physics.hist-ph updates on arXiv.org / 2d
arXiv:2512.18603v1 Announce Type: cross Abstract: Locally covariant algebraic quantum field theory (LCQFT) satisfies Einstein causality through microcausality and operational no-signalling, yet Bell-type correlations persist in entangled field states across spacelike regions. We demonstrate that this apparent tension reflects a fundamental covariance obstruction: no assignment of classical past va
The CHSH Game, Tsirelson’s Bound, and Causal Locality

arXiv:2512.18105v1 Announce Type: cross Abstract: We reformulate the CHSH game in terms of indivisible stochastic processes. Using Barandes’s stochastic-quantum correspondence and its associated definition of causal locality, we present a novel proof of the Tsirelson bound. In particular, we show that unlike the no-signaling principle alone, the postulates defining causally local, indivisible stoc

arXiv:2512.17948v1 Announce Type: cross Abstract: This work presents a reconstructed English edition of the seminal humor anthology \textbf{} (\textbf{Fiziki Shutyat}), originally published in the USSR in 1966. While the Soviet edition served as a significant cultural artifact of the 1960s, a large portion of its content consisted of Russian translations of articles originally written in English.
What is Stochastic Supervenience?

physics.hist-ph updates on arXiv.org / 2d
arXiv:2512.18257v1 Announce Type: new Abstract: Standard formulations of supervenience typically treat higher level properties as point valued facts strictly fixed by underlying base states. However, in many scientific domains, from statistical mechanics to machine learning, basal structures more naturally determine families of probability measures than single outcomes. This paper develops a gener

arXiv:2512.18040v1 Announce Type: new Abstract: Why do physicists almost universally take the direction of positive rotation to be counterclockwise, and three-dimensional coordinates to be right-handed? This paper traces the historical development of these chiral conventions, with an emphasis on the physical quantity whose direction became the focal point of this discussion in the mid-1800s, the m

Their achievements open up possibilities for developing the next generation of quantum technologies, including quantum cryptography, quant

arXiv:2512.19790v1 Announce Type: cross Abstract: We find a necessary condition for subsystems to become entangled after a quantum reference frame transformation. By distinguishing between quantum systems suitable to act as reference frames and physical systems described relative to these frames, we define passive quantum reference frames and show that transformations between these cannot produce
