Âé¶¹ÒùÔºicists reveal how motion can be generated by frustration

When two people want different things, frustration is inevitable. But these non-reciprocal interactions can also occur not just between people, but in the natural world.

Search for skyrmion phenomenon finds even stranger magnetic beaded necklace

Âé¶¹ÒùÔºicists on the hunt for a rarely seen magnetic spin texture have discovered another object that bears its hallmarks, hidden in the structure of ultra-thin magnetic films, that they have called an incommensurate spin crystal.

Second order optical merons, or light pretending to be a ferromagnet

One of the key concepts in physics, and science overall, is the notion of a 'field' which can describe the spatial distribution of a physical quantity. For instance, a weather map shows the distributions of temperature and ...

Nuclear physicists on the hunt for squeezed protons

While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights ...

Light unbound: Data limits could vanish with new optical antennas

Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. They demonstrated the emission of discrete twisting ...
