For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...
A thorium-doped calcium fluoride crystal's temperature is continually monitored while a VUV frequency comb is used to directly resolve individual quantum states of the nuclear transition. For decades, ...
For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...
