The long-range transport of deconfined magnetic hedgehogs
Spintronics is an emerging area of research that aims to develop devices that transmit, process and store information leveraging the intrinsic angular momentum of electrons, known as spin. A key objective of spintronics studies ...
Using drones to create local quantum networks
A team of researchers affiliated with several institutions in China has used drones to create a prototype of a small airborne quantum network. In their paper published in the journal Physical Review Letters, the researchers ...
New mathematical model: How dangerous bacteria form colonies
It can be observed every time you take a shower: Small droplets of water join together to form larger and larger drops—until they are so heavy that they run down the wall. Scientists call this daily-life phenomenon coalescence—which ...

Engineers find a way to control chemical catalysts with sculpted light
Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process—and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in ...

Precise measurements of cluster formation in outer neutron 'skin' of a range of tin isotopes
A large international team of researchers has developed a way to measure cluster formations in the outer neutron 'skin' of a range of tin isotopes rich in neutrons. In their paper published in the journal Science, the group ...
Optical computing at sub-picosecond speeds
Vanderbilt researchers have developed the next generation of ultrafast data transmission that may make it possible to make already high-performance computing "on demand." The technology unjams bottlenecks in data streams ...
