Quantum mechanics for degrees of freedom with velocities small compared with and energies far below pair-production thresholds.

This is an authored directed relation from the source endpoint to the target endpoint.
Nonrelativistic quantum mechanics emerges as a low-energy effective description of suitable QFT sectors when pair creation and relativistic corrections are suppressed.
The target retains the degrees of freedom and interactions relevant below a stated scale or within a stated regime, while higher-energy or unresolved degrees of freedom from the source are integrated out, coarse-grained, or encoded in effective couplings.

Nonrelativistic quantum mechanics specializes quantum theory to low velocities and fixed particle number.
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.
The Coulomb Hamiltonian is the standard nonrelativistic quantum model of electrons and nuclei.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.
