Abstract
Abstract In contrast to previous perturbation calculations that employed the nonrelativistic quantum electrodynamics (QED) method, we have developed the relativistic configuration interaction combined with radiative potential (RCIRP) method to determine the QED correction of 413~nm tune-out wavelength of metastable helium, where the radiative potential operator is directly incorporated into the Dirac-Coulomb-Breit Hamiltonian to account for QED contributions. When the laser polarization vector is parallel or perpendicular to the quantization axis, present results for each magnetic sublevel of $2\,^3S_1$ state are in good accordance with existing theoretical and experimental values, indicating the correctness and effectiveness of the RCIRP method in the determination of QED corrections. Additionally, we find that the static dipole polarizability and tune-out wavelength exhibit high sensitivity to QED effect when the laser polarization vector is parallel to the quantization axis and the magnetic sublevel $M_J=\pm1$, which provides theoretical support for future experimental measurement to test QED calculations.
