Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized laser, where atoms work in concert rather than independently. Publishing their results in Physical ...
Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light on a photonic chip at power levels high enough for real-world use. For the first time, the technique ...
Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum physics, this relativistic ...
Computer chips that cram billions of electronic devices into a few square inches have powered the digital economy and transformed the world. Scientists may be on the cusp of launching a similar technological revolution—this ...
Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.
Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, communications and scientific ...
The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the fact that its simplest form consists of only one proton and one electron, physicists have had a hard ...
The moment nuclear material is produced, processed or purified, it sets off a hidden countdown, marked by the half-life of its radioactive atoms as they begin to decay. For scientists tracking the origins of these substances, ...
For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ytterbium to create a new type of atomic clock that is both highly precise and extremely sensitive to ...
Scientists in the Riccio College of Engineering at the University of Massachusetts Amherst and the University of California Santa Barbara have demonstrated key laser and ion trap components necessary to help drastically shrink ...
