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….
