A University of Vermont physicist and his student wondered if there are systems in the atomic scale that behave like the vibrating motion of a guitar string in the Newtonian world. They found that the answer is yes—and solved Lamb's Model at the atomic scale—a 90-year-old problem in quantum physics. 

Dry processed electrodes that do not require expensive and sometimes toxic solvents and instead use polytetrafluoroethylene as a binder could make battery cell production more environmentally friendly and cost-effective. A research team from the MEET Battery Research Center and the Institute of Business Chemistry at the University of Münster has now developed a method for recycling such dry-processed cathodes — an important step toward circular batteries.

We theoretically and experimentally demonstrate that a cylinder with arbitrary cross section, composed of a homogeneous electromagnetic medium featuring nontrivial second Chern numbers c₂ in a synthetic five-dimensional space, host topologically protected intrinsic Higher-order topological insulators (HOTI) type hinge states. Our work introduces the concept of boundary gauge fields and establishes the link between synthetic-space c₂ and real-space HOTI states.

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.

For the first time, researchers at Umeå University have demonstrated the full capabilities of their large-scale laser facility. In a study published in Nature Photonics, the team reports generating a combination of ultrashort laser pulses, extreme peak power, and precisely controlled waveforms that make it possible to explore the fastest processes in nature.
