The WinFuture article popularizes an optics result whose primary source is Yessenov et al. (arXiv 2025; Optica 2026): a direct observation of a spatially structured Montgomery effect (lensless self-imaging) that generalizes the Talbot effect to aperiodic structures and is claimed to show repeated strongly focused spots (~10 µm) in free space. According to the abstract, a dynamic…

In https://arxiv.org/abs/2510.13124 (Ghalekohneh & Zhao, preprint 2025), a decomposition of non-reciprocal, far-field radiative heat transfer in multi-body emitter networks is described: the heat current is split into an equilibrium contribution with persistent internal circulation and a non-equilibrium contribution for exchange with the environment; the latter is claimed to be engineerable such that “perfect” thermal rectification…

Superconductivity as a Null-Test Regime: Is There an Entropy Residual Beyond the Heat Balance?
•

In the microscopic theory of superconductivity by Bardeen, Cooper & Schrieffer (1957), an energy gap leads to strongly suppressed dissipative quasiparticle contributions at low temperatures, enabling a very low-loss reference mode of operation. Josephson (1962) predicts, for tunnel junctions, a lossless DC supercurrent up to a critical limit as well as a dissipative voltage state…

Starting point is https://www.fr.de/wissen/wie-ein-mysterioeser-neutrino-fund-drei-mysterien-der-physik-loesen-koennte-94157428.html (context); in https://arxiv.org/abs/2505.22722 (preprint, v2 2026), Baker et al. argue that a population of quasi-extremal primordial black holes with “dark U(1)” charge can make the PeV neutrino fluxes of KM3NeT (around 100 PeV) and IceCube (above 1 PeV) simultaneously compatible with gamma-background constraints and LHAASO non-observations—and may even constitute all of the dark…

In Crespi et al. (Monthly Notices of the Royal Astronomical Society, 2026; arXiv 2025), Sgr A* is modeled as a fermionic dark-matter core plus halo; the authors report that the orbital parameters derived for S2 and five G sources differ from a BH-potential variant by less than one percent. Pelle et al. (MNRAS, 2024) ray-trace such fermion cores…

In https://arxiv.org/abs/2504.15495 (preprint; PRL 136 (2026) 057201), Morrell, Elliott & Grier show that two acoustically levitated EPS spheres can enter emergent active stationary states without periodic driving; in one regime, these states break spatiotemporal symmetry and form a continuous classical time crystal. The authors also provide data and analysis code as an OSF repository (https://dx.doi.org/10.17605/OSF.IO/SX7UG).…

In https://arxiv.org/pdf/2504.09148 (preprint, 2026), Ding et al. show that, as the SRG resolution is lowered, a spin → pseudospin transition occurs and the familiar “magic numbers” become visible as robust shell gaps; they also report an increasingly important role of 3N forces for spin–orbit splittings in the low-resolution regime. The numerical data behind all figures are…

Z-Boson Tagging in Heavy-Ion Plasma: Operational Null Tests for “Liquid Primordial Matter”

The news item https://www.ingenieur.de/technik/fachbereiche/rekorde/urknall-im-labor-cern-experiment-zeigt-erstmals-fluessige-urmaterie/ can be traced back to the primary CMS Collaboration work in https://arxiv.org/abs/2507.09307 (preprint, 2025): there, Z-boson tagging correlations of soft charged hadrons in pseudorapidity and azimuth relative to the Z direction in PbPb collisions at 5.02 TeV per nucleon pair are evaluated for the first time, with a pp reference, focusing…

Tracing ΛΛ̄ spin correlations back to the QCD vacuum: FBA handles, null tests, Pass/Fail
•

In https://doi.org/10.1038/s41586-025-09920-0, the STAR Collaboration reports a relative polarization of 18 ± 4% in ΛΛ̄ pairs and a strong dependence on the pair separation, which is read as a decoherence signature. From an FBA perspective, what is exciting is that an alleged “vacuum → detector” path can be operationalized as a channel: Which coarse-graining steps…
