A special bonding state between atoms has been created in the laboratory for the first time: With a laser beam, atoms can be polarized so that they are positively charged on one side and negatively charged on the other. This ...
When a highly diluted gas is cooled to extremely low temperatures, bizarre properties are revealed. Thus, some gases form a so-called Bose-Einstein condensate—a type of matter in which all atoms move in unison. Another ...
Something is happening to the sun. One of the regions of the solar atmosphere currently exhibiting sunspots caught the attention of observatories on July 11, when there was a sudden increase in ultraviolet and X-ray brightness. ...
Metamaterial interface waveguides can confine and guide electromagnetic (EM) waves, which has attractive potential in integrated photonics physics and wireless devices, from radio frequencies to optical bands. The energy ...
Many animals use the Earth's magnetic field for orientation. But exactly how they do this remains for the most part a mystery. At the University of Oldenburg, researchers from across disciplines are working together to solve ...
Korea Advanced Institute of Science and Technology (KAIST) researchers and their collaborators at home and abroad have successfully demonstrated a new platform for guiding the compressed light waves in very thin van der Waals ...
By turning a traditional lab-based fabrication process upside down, researchers at Duke University have greatly expanded the abilities of light-manipulating metasurfaces while also making them much more robust against the ...
Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only been capable of detecting ...
The extreme accuracy and speed of NBA three-pointer Stephen Curry's long-range shots are well known to basketball fans around the world, but accuracy and speed are also a focus of research in biochemical testing. Dr. Yen ...
Optical nanoantennas capable of converting external electromagnetic fields into confined energy and vice versa play a very important role in optical field manipulation. Among them, the bowtie antenna has received extensive ...
