The 121 pages that link to Photon, each with the reason it gives.

• Weak hyperchargeBroader topic: It emerges after symmetry breaking from a mixture of the weak-isospin and hypercharge gauge fields.

• Astronomical instrumentationRelated: Photon counting sets fundamental limits on measurements of faint celestial sources.

• Massless particleBroader topic: Photons are the best-known massless particles and transmit electromagnetic interactions.

• PlasmonCompared with: A photon is a light quantum; a plasmon is a material excitation that can couple to light.

• BKS theoryCompared with: The photon account restores event-by-event conservation that BKS abandoned.

• High-energy astrophysicsRelated: Photon energy distinguishes X-rays and gamma rays from lower-energy light.

• Hong–Ou–Mandel effectNarrower topic: The effect concerns the joint output statistics of individual photons.

• Landau–Yang theoremBroader topic: Two photons are the canonical pair to which the theorem applies.

• Photon epochBroader topic: Photons supplied the dominant energy density named by this epoch.

• PhotonicsNarrower topic: Photonics controls light, whose energy is exchanged in quantized units.

• Radiation (physics)Related: Photons describe electromagnetic radiation in its particle-like interactions.

• Subatomic particleCompared with: Photons are force carriers rather than constituents of ordinary atomic nuclei.

• Tired lightBroader topic: The hypotheses posit that photons lose energy during intergalactic travel.

• BiophotonNarrower topic: A biophoton is a photon distinguished by its biological source, not a different kind of particle.

• Force carrierBroader topic: It mediates electromagnetism and has infinite range.

• Furry's theoremRelated: Each photon vertex contributes one electromagnetic coupling to the loop amplitude.

• Gamma-ray techniquesNarrower topic: Gamma rays are photons distinguished by their origin and energy range.

• Planck postulateRelated: Einstein later treated light itself as consisting of energy quanta.

• QED vacuumRelated: Photon-field modes have vacuum fluctuations even when no real photons are present.

• QuantumBroader topic: A photon is a concrete example of a quantum exchanged by a physical field.

• Scharnhorst effectRelated: The predicted change concerns how photons propagate through the modified vacuum.
