In new research, scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have unveiled a novel approach to understanding stochasticity in tiny magnetic structures. Their insights have the potential to transform computing architectures, leading to more sophisticated neural networks that can learn and adapt like the human brain, as well as enhancing encryption technologies to secure data against increasingly complex cyber threats.

This research is the result of international collaboration involving scientists from the USA, Germany, the UK, the Netherlands, and the Czech Republic. By combining advanced material synthesis, highly sensitive spectroscopy, and complex many-body theory, the team explored the structure of luminous quasiparticles in novel semiconductor magnets. These findings are significant not only for deepening our understanding of magnetic materials but also for driving future technologica

Until now, physicists have struggled to provide a theoretical framework explaining why cracks often branch out and deviate from their expected path, slowing down as a result. Two recent studies from the Weizmann Institute of Science bring order to the disorderly propagation of cracks and show that, although each crack may seem unique, there are quantitative physical parameters that shape the propagation process and explain the formation of asymmetrical crack patterns.

MIT physicists have captured the first images of individual atoms freely interacting in space. The pictures reveal correlations among the “free-range” particles that until now were predicted but never directly observed. Their findings, appearing in the journal Physical Review Letters, will help scientists visualize never-before-seen quantum phenomena in real space.

An exact expression for a key process needed in many quantum technologies has been derived by a RIKEN mathematical physicist and a collaborator. This could help to guide advances in quantum technologies.

Using a clever correction system, a research team was able to significantly improve the quality of electron bunches accelerated by a laser plasma accelerator. This brings the technology a step closer to concrete applications, such as a plasma-based injector for a synchrotron storage ring.
