 Inside the mysterious collapse of dark matter halos Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with normal matter. This self-interacting dark matter may trigger a dramatic collapse inside dark matter halos, heating and densifying their cores in surprising ways. Until now, this crucial middle ground of behavior was nearly impossible to model accurately. The new code makes these simulations faster, more precise, and accessible enough to run on a laptop. A new simulation reveals how colliding dark matter particles could trigger cosmic collapses that shape galaxies—and possibly seed black holes. Credit: AI/ScienceDaily.com For nearly 100 years, dark matter has remained one of the biggest unanswered questions in cosmology. Although it cannot be seen directly, its gravitational influence shapes galaxies and the large-scale structure of the universe. At the Perimeter Institute, two physicists are investigating how ...

 This Quantum Material Breaks the Rules – and Reveals New Physics Quantum physics shows that particles do not behave like solid objects with fixed positions. Instead, they also act like waves, which means their exact location in space cannot be pinned down. Even so, in many practical situations, scientists can still rely on a familiar, classical description. They often picture particles as tiny objects moving through space at a certain speed. This simplified view is especially useful when explaining how electricity moves through metals. Physicists typically describe electric current as electrons rushing through a material, where they are pushed, slowed, or redirected by electromagnetic forces.

 Our elegant universe: rethinking nature’s deepest principle In the Altes Museum in Berlin stands a boy with his arms raised to the heavens. Aside from the right heel, which is slightly arched, this ancient Greek statue is almost perfectly symmetrical. Did the sculptor impose this balance for purely artistic reasons? Hermann Weyl thought not. We are drawn to symmetry, said the German mathematician, because it governs the very order of the universe. In the early 20th century, Weyl helped to uncover symmetry – and, by extension, beauty – as the bedrock of modern physics. Here, it means far more than visual balance. It means that nature behaves the same way in different places, at different times and under countless other changes. Symmetry explains why energy cannot be created or destroyed, and even why many things exist at all. No wonder Weyl thought it had a metaphysical status. Symmetry, he said, “is one idea by which man through the ages has tried to comprehend and create order, b...

Superconductivity Breakthrough: Hidden Order Found Inside Quantum Chaos Physicists have identified a connection between magnetism and an unusual state of matter known as the pseudogap. This phase appears in some quantum materials at temperatures just above where they become superconductors. The discovery may help scientists design new materials with valuable properties, including high-temperature superconductivity, where electrical current moves with no resistance. To uncover this link, researchers used a quantum simulator cooled to temperatures barely above absolute zero. They observed a consistent pattern in how electrons affect the magnetic orientation of nearby electrons as the system cools. Since electrons can have spin up or down, these interactions shape the material’s magnetic behavior. The work marks an important advance in understanding unconventional superconductivity and involved close collaboration between experimental physicists at the Max Planck Institute of Quantum Opti...

The Big Bang’s Biggest Mystery? Dark Matter May Have Been “Red Hot” at Birth A research team from the University of Minnesota Twin Cities and Université Paris-Saclay is questioning a theory about dark matter that has shaped cosmology for decades. Their new work suggests that this mysterious substance may have been “incredibly hot” – moving at nearly the speed of light – when it first formed in the early Universe. The findings were published in Physical Review Letters, the leading journal of the American Physical Society. The study offers fresh insight into how the Universe began and expands the range of possibilities for what dark matter is and how it behaves alongside ordinary matter.
