AC Stark shift of the Cs microwave atomic clock transitions

TL;DR

This paper investigates the AC Stark shift in cesium microwave atomic clocks through theoretical and experimental methods, finding no magic wavelength to eliminate differential shifts between clock states.

Contribution

It provides a combined theoretical and experimental analysis of the AC Stark shift in cesium clocks, revealing the absence of a magic wavelength for zero angular momentum states.

Findings

Theoretical and experimental data agree well.

No magic wavelength exists for the clock transition.

Differential shifts cannot be eliminated at zero angular momentum.

Abstract

We analyze the AC Stark shift of the Cs microwave atomic clock transition theoretically and experimentally. Theoretical and experimental data are in a good agreement with each other. Results indicate the absence of a magic wavelength at which there would be no differential shift of the clock states having zero projections of the total angular momentum.
