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…
