Quantumness via Discrete Structures

arXiv:2512.10063v1 Announce Type: new Abstract: Quantum theory departs from classical probabilistic theories in foundational ways. These departures–termed quantumness here–power quantum information and computation. This thesis charts the role of discrete structures in assessing quantumness, synthesizing elements of my postdoctoral research through this lens. After an introduction to the necessar

arXiv:2511.03843v2 Announce Type: replace-cross Abstract: We resolve Loschmidt’s paradox-the 150-year-old contradiction between time-reversible microscopic dynamics and irreversible macroscopic evolution. The resolution requires both quantum mechanics and classical chaos; neither alone suffices. Quantum uncertainty without chaos produces slow, polynomial spreading-not fundamentally irreversible. C

arXiv:2512.04128v1 Announce Type: new Abstract: Before we discuss the deflection of light in a gravitational field, we give a brief overview of some basic physical formulas on photon properties, generation and propagation. The much debated problems of the redshift and the photon propagation in a gravitational field is then considered and applied to the calculation of the speed of light. Many citat

arXiv:2512.05164v1 Announce Type: cross Abstract: The quantum principle of relativity (QPR) puts forward an ambitious idea: extend special relativity with a formally superluminal branch of Lorentz-type maps, and treat the resulting consistency constraints as hints about why quantum theory has the structure it does [1]. The discussion that followed has emphasized a basic point: writing down coordin

arXiv:2512.07101v1 Announce Type: cross Abstract: This article suggests that thinking about the role of reference frames can provide new insight into Extended Wigner’s Friend scenarios. This involves appealing to symmetries to make a principled distinction between properties of a system which are meaningful only relative to an external reference system and properties which are meaningful without f
The Fine-Structure Constant as a Scaled Quantity

arXiv:2512.07027v1 Announce Type: new Abstract: The fine-structure constant alpha approximately 1/137 is traditionally regarded as a fundamental dimensionless parameter. I argue instead that alpha is a scaled quantity that arises only where the structural scales contributed by classical electromagnetism (e), quantum mechanics (h-bar), and special relativity (c) intersect. None of these theories, t

arXiv:2512.05997v1 Announce Type: new Abstract: In 1857, Kirchhoff published two seminal papers on the motion of electricity in wires. In that work, he was the first to derive what we now call the telegrapher`s equations, which describes the propagation of electromagnetic signals along a cable at the speed of light, in some conditions. How was Kirchhoff able to describe electromagnetic propagation

arXiv:2512.07881v1 Announce Type: cross Abstract: This short note comments on \citet{Aerts2024Origin}, which proposes that ranked word frequencies in texts should be read through the lens of Bose–Einstein (BE) statistics and even used to illuminate the origin of quantum statistics in physics. The core message here is modest: the paper offers an interesting analogy and an eye-catching fit, but sev
Thermal stability originates the vanishing of the specific heats at the absolute zero

arXiv:2512.05129v2 Announce Type: cross Abstract: The relationship between the vanishing of the heat capacities as $T\to0^+$ and the thermal stability is examined. The heat capacities vanish as fast as or faster than $T$ as $T\to0^+$ for states at the phase space boundary ($T=0$) to sustain the standard thermal stability criterion $U_{ss}>0$. Conversely, weakly vanishing heat capacities, which sig

arXiv:2508.01803v3 Announce Type: replace-cross Abstract: We show that the arrow of time is intimately related to the geometry and topology of the whole universe, and is therefore best understood as a cosmological phenomenon.

arXiv:2512.06034v1 Announce Type: cross Abstract: This is a re-editing, which takes quantum mechanics into account, of Wittgenstein’s famous Tractatus. The operation has a playful side in the form, but is a serious attempt to capture possible philosophical implications of the Relational Interpretation of Quantum Mechanics, and formalize the naturalistic third-way between realism and instrumentalis
