As one of the crucial elements of microwave (MW) atomic clocks, Ramsey MW cavities are crucial for assisting MW–atom interactions. A dual‐mode Ramsey cavity for a dual Rb/Cs atomic clock with simultaneous resonances at 6.83 and 9.19 GHz is presented here. The reported cavity, with its high mechanical strength and stability, can excite clock transitions in Rb and Cs atoms in the same zones, thereby providing a compact physical package for a dual Rb/Cs clock. Since both atoms are in the same MW–atom interaction environment, this measurement platform allows for high‐accuracy comparisons.As one of the crucial elements of microwave (MW) atomic clocks, Ramsey MW cavities are crucial for assisting MW–atom interactions.

High-Accuracy Microwave Atomic Clock via Magic Optical Lattice

Xiaoji Zhou, Xuzong Chen, Jingbiao Chen

A microwave atomic clock scheme based on Rb and Cs atoms trapped in optical lattice with magic wavelength for clock transition is proposed. The ac Stark shift of clock transition due to trapping laser can be canceled at some specific laser wavelengths. Comparing with in fountain clock, the cavity related shifts, the collision shift, and the Doppler effect are eliminated or suppressed dramatically in atomic clock when the magic optical lattice is exploited. By carefully analyzing various sources of clock uncertainty, we conclude that a microwave atomic clock with an accuracy of better than $2\times10^{-17}$ is feasible, which is of the same accuracy as the expected best optical atomic clock.A microwave atomic clock scheme based on Rb and Cs atoms trapped in optical lattice with magic wavelength for clock transition is proposed.
