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 ...

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, ...

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 ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

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 ...

Where and why tiny, portable, atomic clocks and their precision are needed. How atomic clocks are no longer room- or box-size arrangements. The size, power, and other metrics of a latest-generation ...

Markus Lutz is CTO and Founder of SiTime Corporation. He is a MEMS expert, a prolific entrepreneur and inventor who holds over 100 patents. Timekeeping might be the unsung hero of human ingenuity. The ...
