(Phys.org)—A team of researchers with members from several institutions in South Korea has developed a means for creating organized yet random mazes on tiny particles. In their paper published on the open access site Science ...
Science fiction is full of fanciful devices that allow light to interact forcefully with matter, from light sabers to photon-drive rockets. In recent years, science has begun to catch up; some results hint at interesting ...

(Phys.org)—In the non-intuitive quantum domain, the phenomenon of counterfactuality is defined as the transfer of a quantum state from one site to another without any quantum or classical particle transmitted between them. ...
With enough computing effort most contemporary security systems will be broken. But a research team at the University of Sydney has made a major breakthrough in generating single photons (light particles), as carriers of ...

(Phys.org)—It was a very good week for physics as a team of researchers from China and Israel made the first observation of the pushing pressure of light—they were able to show the surface of a liquid bending inward when ...
One hundred years after Albert Einstein formulated the general theory of relativity, an international team has proposed another experimental proof. In a paper published today in Nature Physics, researchers from the Hebrew ...
