Plutonium is one of the most complex elements in the periodic table. First synthesized and isolated in 1940 by scientists at the University of California, Berkeley, plutonium has been studied closely for more than eight decades. It's most often associated with its role in nuclear security, but it's also vital to nuclear power, where it is produced in reactors and can be recycled as fuel. Despite plutonium's importance, some of its most fundamental behaviors remain a mystery. https://phys.org/news/2026-06-plutonium-compound-rare-topological-quantum.html General Physics Mon, 29 Jun 2026 19:30:01 EDT news701969521 There is growing demand for smart materials that can change their physical properties in response to various external stimuli such as light, heat, pressure, magnetic fields and electric fields. One such physical property is the magnetic state of material complexes, which depends on electronic spin states. Metal atoms in these complexes can change their spin state—between magnetic and nonmagnetic configurations—in response to light, heat or mechanical pressure. https://phys.org/news/2026-06-synthetic-chemical-framework-magnetic-states.html Analytical Chemistry Mon, 29 Jun 2026 16:10:01 EDT news701965141 An international team of quantum researchers has shown how machine learning can be used to filter a practically infinite number of possible material combinations to identify candidates for superconductivity.

In magnetic semiconductors, one especially useful messenger is the exciton: a pairing of a negatively charged electron and the positively charged "hole" it leaves behind. Until now, excitons in magnetic materials have mostly been used as reporters. They could reveal how spins were arranged or how magnetic waves moved through a material. But Cornell researchers have shown that excitons can do more than observe magnetism. They can actively steer it. https://phys.org/news/2026-06-magnet-excitons-knob-magnetic.html Condensed Matter Thu, 18 Jun 2026 12:00:04 EDT news700995121 A public-private partnership in the Mountain West announced new results today that mark steady progress toward the Department of Energy's goal of fault-tolerant quantum computing, systems large and reliable enough to solve complex problems. https://phys.org/news/2026-06-helios-quantum-tops-fidelity-qubit.html Quantum Physics Wed, 17 Jun 2026 18:40:03 EDT news700920721 Europe's first and only TES spectrometer at a synchrotron source is now in operation at BESSY II, developed within a collaboration between the HZB, the MPI-CEC (Mühlheim-an-der-Ruhr, Germany) and the NIST (Boulder, Colorado, U.S.).
