State-dependent potentials for the $^1\text{S}_{0}$ and $^3\text{P}_{0}$ clock states of neutral ytterbium atoms

Abstract

We present measurements of three distinctive state-(in)dependent wavelengths for the $^1\text{S}_{0}-^3\text{P}_{0}$ clock transition in $^{174}\text{Yb}$ atoms. Specifically, we determine two magic wavelengths at $652.281(21)\,$THz and $542.50205(19)\,$THz, where the differential light shift on the $^1\text{S}_{0}-^3\text{P}_{0}$ clock transition vanishes, and one tune-out wavelength at $541.8325(5)\,$THz, where the polarizability of the $^1\text{S}_{0}$ ground state exhibits a zero crossing. The two new magic wavelengths are identified by spectroscopically interrogating cold $^{174}\text{Yb}$ 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.
