Universal machine-learning interatomic potentials now reach held-out energy and force errors so small that they no longer predict how a model behaves in simulation.
The local effect of an interstitial hydrogen-like particle on localized f electrons was studied in PrPb 3 by means of μ + spin rotation and relaxation.
The microquasar V4641 Sagittarii (V4641 Sgr) has recently been established as one of the most powerful Galactic PeV cosmic-ray accelerators (PeVatrons) through the detection of degree-scale gamma-ray emission to 0.8 PeV.
Previous ALMA observations have revealed unexpectedly strong and rapid variations in Titan's high-altitude equatorial zonal winds, which present a challenge to our understanding of this ....
Designing a scientific instrument tests whether language-model agents can do physics rather than recall it, provided the grading cannot be argued with.
