Physicists make new predictions about the collision of heavy ions at very high relativistic energies

When two heavy ions collide at very high relativistic energies, they penetrate one another, during which they become excited and are slowed down. This "stopping" process can be generated experimentally, as demonstrated on ...

Quantum materials: Electron spin measured for the first time

An international research team has succeeded for the first time in measuring the electron spin in matter—i.e., the curvature of space in which electrons live and move—within "kagome materials," a new class of quantum materials.

The hunt for elusive axion particles: Experiments suggest better methods for exploring the dark sector

Since axions were first predicted by theory nearly half a century ago, researchers have hunted for proof of the elusive particle, which may exist outside the visible universe, in the dark sector. But how does one find particles ...

Thorium-229: How the first nuclear transition can be excited with lasers in the visible wavelength range

The thorium isotope with the mass number 229 (229Th) is highly exciting in many respects—for fundamental physics as well as for future applications, for example in the sense of a nuclear clock.

X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration

Researchers discovered only relatively recently that black hole jets emit X-rays, and how the jets accelerate particles to this high-energy state is still a mystery. Surprising new findings in Nature Astronomy appear to rule ...

Uncovering universal physics in the dynamics of a quantum system

New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium. ...

Latest research provides scientists close-up views of energetic particle jets ejected from the sun

Southwest Research Institute (SwRI) scientists observed the first close-ups of a source of energetic particles expelled from the sun, viewing them from just half an astronomical unit (AU), or about 46.5 million miles. The ...

Modeling of energetic neutral atoms to study solar flares and coronal mass ejections

Solar flares and coronal mass ejections (CME) are two of the most energetic processes in the solar system, showering the Earth's magnetic field with billions of tons of highly energetic plasma gas, potentially disrupting ...

RHIC gets ready to smash gold ions for Run 23

The start of this year's physics run at the Relativistic Heavy Ion Collider (RHIC) also marks the start of a new era. For the first time since RHIC began operating at the U.S. Department of Energy's Brookhaven National Laboratory ...
