When tested against other cutting-edge atomic clocks, including a strontium-based clock and another type of ytterbium clock, the new timepiece demonstrated exceptional stability. The comparisons ...

The next generation of atomic clocks “ticks” at the frequency of a ... two other optical clocks and one microwave clock from PTB were included: an ytterbium single ion clock, a strontium lattice clock ...

Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms ... in the quest to develop increasingly accurate atomic clocks. The spectral resolution achieved in the ...

A standard atomic clock takes a beam of atoms ... Optical clocks such as the aluminum ion, ytterbium, and strontium clocks have much higher resonance frequencies, high enough to be in the spectrum ...

Our research focuses on the development of optical clocks using ultracold atomic systems. By tightly confining ytterbium in the ideal potential of a magic-wavelength optical lattice, the lattice clock ...

In an optical atomic clock, atoms are irradiated by ... systems of PTB participated in the comparisons: a single-ion ytterbium clock, a strontium lattice clock, and a cesium fountain clock.
