Radiative and vacuum effects from QED added to bound-state energies and transition amplitudes, including self-energy and vacuum polarization.

This is an authored directed relation from the source endpoint to the target endpoint.
Bound-electron self-energy is a principal atomic QED correction.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
wp-physics-electron_self_energynist-hydrogenwp-physics-quantum_electrodynamicsThis is an authored directed relation from the source endpoint to the target endpoint.
NRQED organizes radiative, recoil, and relativistic corrections for light atomic bound states.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
wp-physics-quantum_electrodynamicsnist-hydrogenwp-physics-nonrelativistic_qedburgess-eftThis is an authored directed relation from the source endpoint to the target endpoint.
The discrepancy forced renewed scrutiny of bound-state QED, recoil, spectroscopy, and systematic effects.
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
wp-physics-proton_radius_puzzlenist-codata-2022This is an authored directed relation from the source endpoint to the target endpoint.
Atomic QED computes radiative corrections in expansions adapted to bound states, with nonperturbative-in- methods for high .
The target is recovered from the source either in a stated mathematical or asymptotic limit, or through a quantitatively controlled approximation with identified small parameters or omitted terms. The edge label and detail must state which case applies and its regime of validity.

Vacuum polarization modifies the nuclear Coulomb potential.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

This is an authored directed relation from the source endpoint to the target endpoint.
The observed splitting is a foundational benchmark for atomic QED corrections.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
wp-physics-lamb_shiftnobel-lambnist-qed-testsThis is an authored directed relation from the source endpoint to the target endpoint.
Self-energy and vacuum polarization dominate the Lamb shift, with recoil and nuclear-size contributions also relevant.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
