First dreamed up decades ago, the world's first nuclear clocks are set to improve quickly, becoming more precise and aiding the hunt for dark matter.

Two independent teams of scientists have created the first functional clocks that can keep ultraprecise time using the nuclei ...

Keeping time is easy, keeping precise time is hard, but a new type of clock based on atomic nuclei has pushed time-keeping ...

Nuclear clocks should be more robust and portable than the best available clocks today because nuclei are hard to perturb and are protected in a crystal. Creating a nuclear clock is “a dream come ...

The demonstrated system achieved short-term fractional frequency stability highlighting the platform’s potential for future chip-scale quantum ...

By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that could lead to even more precise clocks and new ways to search for dark ...

Atomic clocks are established as the most precise timekeepers created. Atomic clocks work by deploying lasers to measure the vibrations of atoms (electromagnetic signals). By atoms oscillating at a ...

Although there are many variables in life, there's one metric by which our existence is strictly measured: time. We think of it as rigid, smooth, and unidirectional – the arrow of time flies straight ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

"This book provides a introduction to the physics of time and time measurement, from an historical perspective to the modern day. It discusses the stability and accuracy of atomic frequency standards, ...
