Named Effects
Named effects are useful handles for recurring physical mechanisms, but the name alone rarely specifies the approximations, geometry, sign conventions, or model assumptions. These entries give compact definitions and route to the canonical teaching pages where the site has a fuller treatment.
Entries
Section titled “Entries”| Entry | Compact Meaning | Canonical Route |
|---|---|---|
| Aharonov–Bohm Effect | Gauge-invariant phase from enclosed electromagnetic flux even when local fields vanish along the paths. | Aharonov–Bohm Effect: First Encounter |
| Quantum Hall Effect | Quantized Hall response in two-dimensional electron systems, stabilized by gaps, topology, and disorder physics. | Landau Levels and Chern Numbers |
| Zeeman Effect | Splitting or shifting of quantum levels by magnetic-field coupling to magnetic moments. | Rotor in External Fields and spin pages |
| Stark Effect | Splitting or shifting of levels by electric-field coupling to dipole moments or polarizability. | Rotor in External Fields and perturbation theory |
| Josephson Effect | Phase-coherent current through a weak link between superconductors. | Tunneling Applications: First Encounters |
How to Read These Entries
Section titled “How to Read These Entries”Each named effect entry separates:
- the core physical mechanism;
- the minimal formula or scale;
- the nearest canonical teaching page;
- common mistakes about scope and conventions;
- standard sources for the phenomenon.
The entries are not priority claims, historical essays, or substitutes for detailed spectroscopy, transport, or condensed-matter treatments.
