We present an extended model for the lattice-induced light shifts of the clock frequency in
optical lattice clocks, applicable to a wide range of operating conditions. The model
extensions cover radial motional states with sufficient energies to invalidate the harmonic
approximation of the confining potential. We reevaluate lattice-induced light shifts in our Yb
optical lattice clock with an uncertainty of 6.1× 10− 18 under typical clock operating
conditions.
