C8 – Methods, Data & Reproducibility
-
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…

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…
