Physicists circumvent centuries-old theory to cancel magnetic fields
A team of scientists including two physicists at the University of Sussex has found a way to circumvent a 178-year old theory which means they can effectively cancel magnetic fields at a distance. They are the first to be ...

Topology gets magnetic: The new wave of topological magnetic materials
The electronic structure of nonmagnetic crystals can be classified by complete theories of band topology, reminiscent of a "topological periodic table." However, such a classification for magnetic materials has so far been ...

Weak equivalence principle violated in gravitational waves
The Weak equivalence principle (WEP) is a key aspect of classical physics. It states that when particles are in freefall, the trajectories they follow are entirely independent of their masses. However, it is not yet clear ...

The experimental demonstration of entanglement between mechanical and spin systems
Quantum entanglement is the basic phenomenon underlying the functioning of a variety of quantum systems, including quantum communication, quantum sensing and quantum computing tools. This phenomenon results from an interaction ...
Record neutron numbers at Sandia Labs' Z machine fusion experiments
A relatively new method to control nuclear fusion that combines a massive jolt of electricity with strong magnetic fields and a powerful laser beam has achieved its own record output of neutrons—a key standard by which ...
