World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

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, ...

What looks like an aerial shot of an alien landscape is actually a scanning electron microscope view of a test glass surface, acquired as part of a project to improve the lifetime of spaceborne atomic ...

For many years, scientists all around the world have been working towards this goal, now suddenly things are happening very fast: it was only in April that a team led by Prof Thorsten Schumm (TU Wien, ...

For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new ...

Precision timekeeping has been rapidly evolving from astronomical observations in ancient times to mechanical clocks to quartz to present-day quantum atomic clocks, becoming a critical requirement in ...

An international research team has taken a decisive step toward a new generation of atomic clocks. At the European XFEL X-ray laser, the researchers have created a much more precise pulse generator ...
