How Quantum Contextuality disappears in the Classical Limit

Arthur C. R. Dutra, Roberto D. Baldijao, Marcelo Terra Cunha · 2026

The emergence of classicality is fundamentally driven by the interaction between a quantum system and its environment. Foundational open-system approaches, notably the Caldeira-Leggett model, successf…

Contextuality from the Projector Overlap Matrix

Ali Can Gunhan, Semahi Serhat Aksoy, Zafer Gedik · 2026

We place several known indicators of Kochen--Specker contextuality -- the KCBS correlator $\chi$, the contextual fraction $\CF$, the Shannon-entropic $n$-cycle inequality of Chaves and Fritz, and the …

Boxing inequalities for relative fractional perimeter and fractional Poincar\'e-type inequalities on John domains with the BBM factor

Manzi Huang, Panu Lahti, Jiang Li, Zhuang Wang · 2026

For $0<\delta,\tau<1$ and $1\le s\le \frac{n}{n-\delta}$, we prove that for a given $s$-John domain $\Omega\subset \mathbb{R}^n$, the following Boxing inequality holds for every Lebesgue measurable …

SAT + NAUTY: Orderly Generation of Small Kochen-Specker Sets Containing the Smallest State-independent Contextuality Set

Zhengyu Li, Curtis Bright, Stefan Trandafir, Adan Cabello, Vijay Ganesh · 2026

We present a search for small Kochen-Specker (KS) sets in dimension 3, specifically targeting extensions of the 13-ray Yu-Oh set, which has been proven to be the minimal witness to state-independent c…

Quantum Correlations in Classical Systems

Ghenadie N. Mardari · 2026

A classical fluid splitter produces the same patterns of energy redistribution as a Stern-Gerlach quantum device, with rotationally invariant coefficients of correlation between molecular paths. Alter…

Multifractal Analysis, Liv\v{s}ic Rigidity, and Fluctuation Theorems for Axiom A Diffeomorphisms: The Pesin Formula and the Gallavotti-Cohen Symmetry

Abdoulaye Thiam · 2026

This Part develops structural consequences of the thermodynamic formalism for Axiom A diffeomorphisms. The Pesin Entropy Formula equates the metric entropy of the SRB measure to the sum of positive Ly…

Warring Contextualities -- Provably Classical vs Provably Nonclassical

Enrico Bozzetto, Jonte R. Hance · 2026

In the literature, there are two differing definitions of contextuality: Kochen and Specker's, and Spekkens' (or ``generalised''). However, researchers using one of these definitions rarely consider t…

Perspectivist Account of Truth-Theoretic Semantics in Quantum Mechanics

Vassilios Karakostas · 2026

According to various no-go results in the foundations of quantum mechanics, for any system associated to a Hilbert space of dimension higher than two, it is not possible to assign definite truth value…

A characterization of Cohen-Macaulay rings in terms of levels of perfect complexes

Naoya Hiramatsu, Yuki Mifune, Ryo Takahashi · 2026

Let $R$ be a commutative noetherian ring, and let $C$ be a semidualizing $R$-module. In this paper, we study levels of bounded complexes of finitely generated $R$-modules with respect to the full subc…

A time grating approach to ultrahigh-Q guided mode resonance

Youxiu Yu, Xiaofeng Xu, Yang Long, Gui-Geng Liu, Dongliang Gao, Xiao Lin, Hao Hu · 2026

Guided mode resonance (GMR), the resonant coupling of free-space light into leaky waveguide modes, is traditionally achieved with periodic patterned structures. However, this approach makes its key pr…

Goos-H\"anchen Shift in $\mathcal{PT}$-Symmetric and Passive Cavity Optomechanical Systems

Shah Fahad, Gao Xianlong · 2026

We theoretically investigate the control of the Goos-H\"anchen shift (GHS) of a reflected weak probe field in both parity-time ($\mathcal{PT}$)-symmetric and conventional optomechanical systems. The p…

Conclusive Identification Via Noisy Classical Channel: Superactivation and Quantum Advantage

Anushko Chattopadhyay, Ambuj, Rakesh Das, Smritikana Patra, Chitrak Roychowdhury, Manik Banik, Amit Mukherjee · 2026

We introduce conclusive identification task for classical channels: a receiver identifies transmitted inputs without error when possible, and responds inconclusively when outputs are ambiguous. For a …

AKE principles for deeply ramified fields

Franziska Jahnke, Jonas van der Schaaf · 2026

We study the model theory of deeply ramified fields of positive characteristic. Generalizing the perfect case treated in work by Jahnke and Kartas on the model theory of perfectoid fields, we obtain A…
