Team accomplishes precise measurements of the heaviest atoms

An international research team has successfully conducted ultra-precise X-ray spectroscopic measurements of helium-like uranium. The team, which includes researchers from Friedrich Schiller University Jena and the Helmholtz Institute Jena (both in Germany), has achieved results demonstrating their success in disentangling and separately testing one-electron two-loop and two-electron quantum electrodynamic effects for extremely strong Coulomb fields of the heaviest nuclei for the first time.

New method flips the script on topological physics

The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable—and above all reliable—properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model.

Rare decay of the Higgs boson may point to physics beyond the Standard Model

Particle physicists have detected a novel decay of the Higgs boson for the first time, revealing a slight discrepancy in the predictions of the Standard Model and perhaps pointing to new physics beyond it. The findings are published in the journal Physical Review Letters.

Validating the low-rank hypothesis in complex systems

In a new study, scientists have investigated the pervasive low-rank hypothesis in complex systems, demonstrating that despite high-dimensional nonlinear dynamics, many real networks exhibit rapidly decreasing singular values, supporting the feasibility of effective dimension reduction for understanding and modeling complex system behaviors.

Gravity helps show strong force strength in the proton

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the swirl of gigantic galaxies. These awesome displays showcase gravity's influence at the largest scales of matter. Now, nuclear physicists are discovering that gravity also has much to offer at matter's smallest scales.

The physics behind 300-year-old firefighting methods could inform knowledge of how our hearts work

Today, water pressure technology is ubiquitous, and any person who showers, waters a garden, or fights fires is benefiting from the technology devised to harness it. In the 17th and 18th centuries, though, a steady stream of water not punctuated by pressure drops was a major breakthrough.
