Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint ...
Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply ...
Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting how multiple intermolecular ...
Scientists from the Faculty of Physics at the University of Warsaw, in collaboration with teams from the National University of Singapore and Radboud University in the Netherlands, have observed single-photon emission from ...
In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 indistinguishable neutral atoms—an effect that has been predominantly observed in photonic systems.
Peering far into the distant, high-redshift universe, the James Webb telescope has discovered an abundance of small red galaxies known as the Little Red Dots. From their observations, astronomers believe that at least some ...
Astronomers have identified one of the most distant candidate galaxies known to leak ionizing radiation—the same kind of radiation thought to have transformed the early universe during the epoch of reionization.
Giant mirrors in space have been a staple of science fiction for decades. But so far, there's been very little work looking at the actual physics behind the concept—possibly because we're still so far from making them ourselves. ...
When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool? Researchers have now demonstrated ...
The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in Earth's protective layer of stratospheric ozone. Industrial chemicals known as chlorofluorocarbons (CFCs), then widely used as ...
