Where Does the Quantum World End? An Operational FBA View on Nanoparticle Interference (MUSCLE)
•
5 min read
In 2026, a Vienna team demonstrated quantum interference of sodium nanoparticles with more than 7,000 atoms (masses >170,000 Da) in the MUSCLE interferometer—setting a new size record for matter-wave interference. “Where does the quantum world end?” can thus be sharpened experimentally: How large may an object become, and how “classical” may its environment be, before…

In https://www.frame-budget-approach.eu/PDF/DE/FBA_09_Kosmische_Dynamik_Time_Dilation_Inflation_TDI.pdf (PDF/preprint, 2026), “accelerated expansion” is formulated as time-dilation inflation via the factor χ(t) and operationalized as overdetermined through distance data, chronometers, redshift drift, and SN time dilation in null tests N1–N3. In the same part, “before time” is not treated as t<0 physics, but as an operational question about the start of the…

In a new CMS analysis at the CERN LHC, Z bosons are used as a “tag” in PbPb heavy-ion collisions, and in Z–hadron correlations a soft depletion/wake signature is found on the away-side. If a “cosmic primordial soup” truly responds like a fluid, then exactly such a pattern should show up as a precise, repeatable…

In the Spektrum podcast on warm inflation (discussed since 1995), the focus is on a new PRL/preprint model (2025) that contrasts the standard assumption of cold inflation (near-vacuum during inflation, reheating afterwards) with a sustained thermal bath throughout the inflationary phase. This shifts the emphasis: not only how fast space expands, but whether particle production/dissipation…

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?
•
6 min read
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…
