Improved limits for violations of local position invariance from atomic clock comparisons

R. Lange, N. Huntemann, J. M. Rahm +6

We compare two optical clocks based on the $^{2}$ S $_{1/2} (F = 0) \to^{2}$ D $_{3/2} (F = 2)$ electric quadrupole (E2) and the $^{2}$ S $_{1/2} (F = 0) \to^{2}$ F $_{7/2} (F = 3)$ electric octupole (E3)…

Long term measurement of the $^{87}$ Sr clock frequency at the limit of primary Cs clocks

R. Schwarz, S. Dörscher, A. Al-Masoudi +7

We report on a series of 42 measurements of the transition frequency of the 429~THz (5s $^{2}$ )~ $^{1}$ S $_{0}$ --(5s5p)~ $^{3}$ P $_{0}$ line in $^{87}$ Sr taken over three years from 2017 to 2019.…

Advances in the accuracy, stability, and reliability of the PTB primary fountain clocks

S. Weyers, V. Gerginov, M. Kazda +4

Improvements of the systematic uncertainty, frequency instability, and long-term reliability of the two caesium fountain primary frequency standards CSF1 and CSF2 at PTB (Physikali…
