Physicists report creating a time crystal with unprecedented detail, showing stable oscillations without energy loss. The ...
Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy transitions in the nuclei of atoms and could become the ...
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 ...

New Ion Crystal Clock Achieves Unprecedented Accuracy
Recent research published in Physical Review Letters by PTB (Physikalisch-Technische Bundesanstalt) details the development ...
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 ...
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.
Measuring 2.5 x 2.0 x 0.9 mm, the NZ2520 crystal clock oscillator is claimed to be the industry's smallest and thinnest such part. The SMT-packaged oscillator is available in frequencies from 1.5 to ...
An electronic system requires a reliable, precision timing reference: the system clock. We examine and compare two forms of system clocks, the Crystal Oscillator and the Phase Locked Loop Synthesizer ...
