Next-to-leading power terms can be significant in slepton pair production
What the study found Next-to-leading power contributions in the threshold variable can be significant for inclusive slepton pair production. The authors also report that existing calculations underestimate the scale error for large slepton masses. Why the authors say this matters The study suggests that accounting for these next-to-leading power effects is important when assessing theoretical…
Spectral localizer matches local Chern and winding markers
What the study found The study explicitly demonstrates that the spectral localizer is equivalent to local Chern and winding markers. The authors show that Chern and winding markers appear as leading-order terms in a perturbative expansion in the spectral localizer parameter κ. Why the authors say this matters The authors say this matters because the…
THERMO-NET reduces dissipation in modeled thermal systems
What the study found THERMO-NET is a physics-informed artificial intelligence framework that the authors say can model, predict, and actively suppress irreversible entropy production in several high-density computational and thermal settings. The abstract reports improved performance across five tested regimes, including quantum hardware and nano-scale thermal networks. Why the authors say this matters The authors…
Semi-visible dark jets may be probed at FCC-ee
What the study found The study finds that Higgs-boson-mediated production of dark quarks at the Future Circular Collider in electron-positron collisions could produce semi-visible jets, meaning jets made of both visible and invisible particles. The authors report that a graph neural network jet tagger helps improve sensitivity, especially when the invisible part of the signal…
LSC 6.0 lowers the Gallium anomaly bias estimate
What the study found LSC 6.0 is a phenomenological framework that combines weak propagation effects with anisotropic detector response in neutrino physics. The abstract says its central result is that this coupled mechanism reduces the energy-scale bias needed to explain the Gallium anomaly from about 10% to about 3–6%. Why the authors say this matters…
Island shapes show differing self-affine scaling
What the study found Earth's islands show different self-affine scaling behavior depending on the geometric feature measured. The authors report four Hurst exponent estimates, which are roughness measures for self-affine surfaces, and these estimates are sorted by increasing expected influence of coastal processes. Why the authors say this matters The study suggests that these patterns…
Glitches can mildly bias EMRI inference in LISA
What the study found Streams of transient, non-Gaussian noise artifacts called glitches can bias inference for extreme mass ratio inspirals (EMRIs) in the Laser Interferometer Space Antenna (LISA), but the effect is relatively small when the glitches are moderately mitigated. The study found that EMRI inference is more robust to glitches than inference for some…
Capacitance bridge measures light-induced force on a cantilever
What the study found The study reports a tabletop interferometer based on a mechanical cantilever that can measure the radiation force exerted by light. It uses a capacitance bridge to detect very small capacitance changes caused by light-driven motion of the cantilever. Why the authors say this matters The authors say the experiment uses equipment…
Single fluxonium qubit shows microwave EIT, delay, and storage
What the study found A single fluxonium qubit in a microwave waveguide showed electromagnetically induced transparency (EIT), a slowdown of light with a delay time of 217 ns, and photon storage. Why the authors say this matters The authors conclude that these results highlight potential use of the system as a phase shifter or quantum…
Shear before gelation did not change final geopolymer strength
What the study found Shearing a sodium silicate-activated metakaolin geopolymer before its critical gel point did not change the critical gel time, the viscoelastic properties after the set point, or the 7-day compressive strength. The study also reports that metakaolin geopolymers kept their compressive strength after six months of testing in low Earth orbit. Why…
