In an optical atomic clock, atoms are irradiated with laser light. If the laser has exactly the right frequency, the atoms change their quantum mechanical state. All external influences on the atoms ...

Scientists developed a highly accurate optical ion clock, improving time measurement precision by 1,000 times.

Cs2CoCl4 single crystals exhibit unique negative photoconductivity and volatile resistive switching, paving the way for ...

Recent research published in Physical Review Letters by PTB (Physikalisch-Technische Bundesanstalt) details the development ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

The UAE on Friday recorded its coldest day so far this winter — and much to residents' delight, frost and ice crystals were spotted on the country's highest mountain. Temperatures dropped to a ...

A team of chemical engineers at Deakin University, working with colleagues from the University of Western Australia, the University of Sydney and Monash University, all in Australia, has found that a ...
