Tune-out wavelengths of the hyperfine components of the ground level of $^{133}$Cs atoms (2010.11005v1)

Abstract: The static and dynamic electric-dipole polarizabilities and tune-out wavelengths for the ground state of Cs atoms are calculated by using a semiempirical relativistic configuration interaction plus core polarization approach. By considering the hyperfine splittings, the static and dynamic polarizabilities, hyperfine Stark shifts, and tune-out wavelengths of the hyperfine components of the ground level of $^{133}$Cs atoms are determined. It is found that the hyperfine shifts of the first primary tune-out wavelengths are about $-$0.0135 nm and 0.0106 nm, which are very close to the hyperfine interaction energies. Additionally, the contribution of the tensor polarizability to the tune-out wavelengths is determined to be about $10^{-5} \sim 10^{-6}$ nm.
