Measurement of a Wavelength of Light for Which the Energy Shift for an Atom Vanishes

Dynamic polarizabilities for the low-lying states of Ca+

“…The ratios are in very good agreement with the MBPT-SD ratios. It should be noted, that the line strength ratios for the resonant transition of potassium have been measured to be very close to 2.0 [17] and DFCP and MBPT-SD calculations also predict line strength ratios very close to 2.0 [17,56].…”

“…A parameter related to the magic wavelength is the tune-out wavelength. The tune-out wavelengths for an atomic state are the wavelengths at which the polarizability for that state goes to zero [15][16][17]. It should be noted that most atomic states have a number of tune-out wavelengths just like most atomic transitions have a variety of magic wavelengths.…”

Tune-out wavelengths for the alkaline-earth-metal atoms

“…Atoms trapped in an optical lattice can be released by changing the wavelength of the trapping laser to that of the tune-out wavelength for that atom. Very recently, tune-out wavelengths have been measured for the rubidium [5] and the potassium atoms [6]. The advantage of a tune-out wavelength measurement is that it is effectively a null experiment, it measures the frequency at which the polarizability is equal to zero.…”

“…The wavelengths at which the polarizability goes to zero are called the tune-out wavelengths [3][4][5][6][7]. Atoms trapped in an optical lattice can be released by changing the wavelength of the trapping laser to that of the tune-out wavelength for that atom.…”

Decoherence Spectroscopy for Atom Interferometry

“…Our motivation is to improve measurements of tune-out wavelengths, λ zero , made with an atom interferometer [34][35][36]. These λ zero measurements test theoretical polarizability spectra α(ω) described in references [22][23][24][25][26][27][28][29][30][31][32][33].…”
