http://www.cardinalxtal.comThe term “frequency jitter” has become popular in the last few years to define the short-term stability of a frequency source. A ...

Keeping perfect time is far trickier than it sounds. The world’s best clocks that are used for GPS navigation, satellite communication, and testing fundamental physics depend on carefully controlled ...

Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a separate line of theoretical work suggesting that time crystals, exotic quantum ...

The Model 680 is a small sized, light weight and rugged HCMOS crystal clock oscillator for operations under extended temperatures and stringent environments. The Model 680 is a small sized, light ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

Physicists confirmed the full two-dimensional six-state clock model in atomically thin nickel phosphorus trisulfide, ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...
