Photonics chip allows light amplification

 Physics General News
 30 November 2022
The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern information society. In optical telecommunications, the choice of 1550 nm wavelength band is motivated not...

The Kibble-Zurek mechanism for nonequilibrium phase transitions

 Physics General News
 30 November 2022
The Kibble-Zurek (KZ) mechanism, confirmed experimentally only for equilibrium phase transitions, is also applicable for non-equilibrium phase transitions, as is now shown by Tokyo Tech researchers in a new study. The KZ mechanism is characterized by the formation of topological defects during...

Gorgeous rainbow-colored, stretchy film for distinguishing sugars

 Nanotechnology News
 30 November 2022
Rainbows and sugar may conjure up images of a certain leprechaun-branded breakfast cereal. But now, researchers in ACS Nano report a kaleidoscope-like film for telling different sweeteners apart that displayed multiple colors when stretched by hand. When evenly stretched with a simple apparatus, the...

Team creates nano-magnets that could restore damaged nerve cells

 Nanotechnology News
 29 November 2022
Neurons are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between. Neurons, also called nerve...
