Magic wavelength of the 138Ba+ 6s\;2S1/2-5d\;2D5/2 clock transition
Abstract
The zero crossing of the dynamic differential scalar polarizability of the S1/2-D5/2 clock transition in 138Ba+ has been determined to be 459.1614(28)\,THz. Together with previously determined matrix elements and branching ratios, this tightly constrains the dynamic differential scalar polarizability of the clock transition over a large wavelength range ( 700\,nm). In particular it allows an estimate of the blackbody radiation shift of the clock transition at room temperature.
