State-dependent potentials for the ^1S_0 and ^3P_0 clock states of neutral ytterbium atoms

We present measurements of three distinctive state-(in)dependent wavelengths for the ^1S_0-^3P_0 clock transition in ^174Yb atoms. Specifically, we determine two magic wavelengths at 652.281(21)THz and 542.50205(19)THz, where the differential light shift on the ^1S_0-^3P_0 clock transition vanishes, and one tune-out wavelength at 541.8325(5)THz, where the polarizability of the ^1S_0 ground state exhibits a zero crossing. The two new magic wavelengths are identified by spectroscopically interrogating cold ^174Yb atoms on the clock transition in a one-dimensional optical lattice. The ground-state tune-out wavelength is determined via a parametric heating scheme. With a simple empirical model, we then extrapolate the ground and excited state polarizability over a broad range of wavelengths in the visible spectrum.
