Casimir interactions as a probe of broadband optical response IJQF Weekly Papers • quant-ph updates on arXiv.org / 6h arXiv:2601.10118v1 Announce Type: new Abstract: Casimir forces arise from quantum electromagnetic fluctuations and depend on the dielectric response of interacting materials across the entire frequency spectrum. Although this dependence is central to Lifshitz theory of the Casimir effect, the formulation of the force… Read more →
Hardy nonlocality for entangled pairs in a four-particle system IJQF Weekly Papers • quant-ph updates on arXiv.org / 13h 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… Read more →
Coexistence of Anderson Localization and Quantum Scarring in Two Dimensions IJQF Weekly Papers • quant-ph updates on arXiv.org / 1d 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….

AC Stark effect or time-dependent Aharonov-Bohm effect for particle on a ring IJQF Weekly Papers • quant-ph updates on arXiv.org / 7h arXiv:2512.15935v1 Announce Type: new Abstract: We study the effect of a time-varying solenoidal vector potential for a quantum particle confined to a ring. The setup appears to be a time-varying version of the Aharonov-Bohm effect, but since the particle moves… Read more →
Quantumness via Discrete Structures IJQF Weekly Papers • quant-ph updates on arXiv.org / 7h 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… Read more →
Physical Probability in the Everett Interpretation and Bell Inequalities IJQF Weekly Papers • physics.hist-ph updates on arXiv.org / 2d arXiv:2512.00575v1 Announce Type: cross Abstract: I define a notion of local causality LOC closely modelled on the Bell principle, construed as the condition that single case probabilities cannot be modified by actions at spacelike separation. The new principle, like that of Bell, forces… Read more →
Higher-order Zeno sequences IJQF Weekly Papers • quant-ph updates on arXiv.org / 1d arXiv:2511.20792v1 Announce Type: new Abstract: The quantum Zeno effect typically refers to freezing the dynamics of a quantum system through frequent observations. In general, quantum Zeno dynamics is obtained with an error of order $\mathcal{O}(1/N)$, where $N$ is the number of projective measurements performed within a fixed evolution time…. Read more →
On the Potential of Microtubules for Scalable Quantum Computation IJQF Weekly Papers • quant-ph updates on arXiv.org / 20h arXiv:2505.20364v2 Announce Type: replace-cross Abstract: We examine the quantum coherence properties of tubulin heterodimers arranged into the protofilaments of cytoskeletal microtubules. In the physical model proposed by the authors, the microtubule interiors are treated as high-Q quantum electrodynamics (QED) cavities that can support… Read more →
Local arrows of time in quantum many-body systems IJQF Weekly Papers • quant-ph updates on arXiv.org / 10h arXiv:2511.09758v1 Announce Type: new Abstract: We demonstrate that in quantum many-body systems, local arrows of time can differ from the global time $t$ induced by Hamiltonian evolution. That is, within a quantum many-body system, the flow of time can be relative to each observer… Read more →
Expectation-Realization Interpretation of Quantum Superposition IJQF Weekly Papers • 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… Read more →
Entanglement and Thermodynamic Scaling Laws in Quantum Superabsorption IJQF Weekly Papers • quant-ph updates on arXiv.org / 11h arXiv:2510.26373v1 Announce Type: new Abstract: Quantum batteries (QBs) exploit collective quantum resources to surpass the limits of classical energy storage and power delivery. We analyze $N$-qubit cavity-coupled QBs governed by Dicke and Tavis–Cummings models under Gaussian driving and open-system dynamics. Finite-size scaling laws $\mathcal{O}(N)\!\sim\!N^{\alpha}$… Read more →
