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 ...

Magnetic effect without a magnet

Electric current is deflected by a magnetic field—in conducting materials, this leads to the so-called Hall effect. This effect is often used to measure magnetic fields. A surprising discovery has now been made at TU Wien, ...

Physicists discover new physical effect

Scientists have found that a perpendicular magnetic field makes electrically neutral quasiparticles (excitons) in semiconductors behave like electrons in the Hall effect. This discovery will help researchers to study the ...

Toward next-generation molecule-based magnets

Magnets are deployed in a range of technology applications, including satellites, telephones and refrigerator doors. However, they are made up of heavy, inorganic materials whose component elements are, in some cases, of ...
