“…Measurement of the magic wavelength here is in some respects in analogous to a measurement of the longest tune-out wavelength for neutral potassium [56]. Zero field shift wavelengths measured in the spin-orbit energy gap of the resonant transition are strongly dominated by the large and opposite polarizability contributions of the two members of the spin-orbit doublet [56,75]. This makes it possible to accurately determine the oscillator strength ratio, i.e.…”

The dynamic polarizabilities of the 4s, 3d and 4p states of Ca + , are calculated using a relativistic structure model. The wavelengths at which the Stark shifts between different pairs of transitions are zero are computed. Experimental determination of the magic wavelengths can be used to estimate the ratio of the f 3d J →4p J ′ and f4s 1/2 →4p J ′ oscillator strengths. This could prove valuable in developing better atomic structure models and in particular lead to improved values of the polarizabilities needed in the evaluation of the blackbody radiation shift of the Ca + ion.

“…Light species like lithium offer particularly fruitful interplay between theory and experiment because of the high-accuracy calculational techniques available for few-electron species. Ab initio calculations in atoms with few electrons can account for electron-electron correlations using the variational Hylleraas basis set [43][44][45][46][47]. The Hylleraas calculations are expected to produce the most accurate results in lithium, where they serve as a benchmark for approximation methods applicable to heavier atoms [48].…”

“…Precision measurements of TO wavelengths [31][32][33][34][35][36][37][38] may also be used to test all-order atomic theory [24,39,40] and QED [41,42]. Ab initio calculations in simple atoms with three or fewer electrons admit explicit accounting of electron-electron correlations [43][44][45][46][47]. Comparing theory and experiment for lithium serves to benchmark approximation methods applicable to heavier atoms [48].…”

Measurement of a Li7 tune-out wavelength by phase-patterned atom interferometry

Atom interferometers typically use the total populations the interferometer's output ports as the signal, but finer spatial structure can contain useful information. We pattern a matter-wave phase profile onto an atomic sample. An interferometer translates the phase into a measurable pattern in the atomic density that we use perform the first direct precision measurement of the 7 Li tune-out wavelength near 671 nm. Expressed as a detuning from the |2S 1/2 , F =2 →|2P 1/2 , F =2 transition, we find 3329.3(1.4) MHz for the tensor-shifted tune out of the |2S 1/2 , F =2, mF =0 state with σ ± light polarization and 3310.1(4.9) MHz for the tune out of the the scalar polarizability. This technique may be generalized for directly sensing spatially varying phase profiles.

“…This is about the same size as the known error in the polarizability in similar calculations for Li, namely, 0.10 a.u. or 0.06% [43,44]. So the assignment of an uncertainty of 0.11 a.u.…”
