Analysis of atomic-clock data to constrain variations of fundamental constants

Nathaniel Sherrill, Adam O. Parsons, Charles F. A. Baynham +13

We present a new framework to study the time variation of fundamental constants in a model-independent way. Model independence implies more free parameters than assumed in previous…

Frequency ratio of two optical clock transitions in $^{171}$ Yb $^{+}$ and constraints on the time-variation of fundamental constants

R. M. Godun, P. B. R. Nisbet-Jones, J. M. Jones +7

Singly-ionized ytterbium, with ultra-narrow optical clock transitions at 467 nm and 436 nm, is a convenient system for the realization of optical atomic clocks and tests of present…

Cancellation of the collisional frequency shift in caesium fountain clocks

K. Szymaniec, W. Chalupczak, E. Tiesinga +3

We have observed that the collisional frequency shift in primary caesium fountain clocks varies with the clock state population composition and, in particular, is zero for a given…
