Atomic structure based on Dirac electrons and relativistic electromagnetic interactions, increasingly important for high nuclear charge and precision.

This is an authored directed relation from the source endpoint to the target endpoint.
Relativistic atomic structure replaces or augments the nonrelativistic Hamiltonian with Dirac-based and QED-matched descriptions when or required precision makes relativistic effects important.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.

This is an authored directed relation from the source endpoint to the target endpoint.
Fine structure arises from the relativistic atomic Hamiltonian and its low-energy expansion.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
