Charge photon
WebCharges (electrons, positrons, nuclei) are accompanied by (''emit'') an electromagnetic field - a soft virtual photon cloud in terms of QED. Photons are elementary excitations of the quantum electromagnetic field. They do not carry charge.

In electronics shot noise originates from the discrete nature of electric charge. Shot noise also occurs in photon counting in optical devices, where shot noise is associated with the particle nature of light.

WebDec 27, 2024 · Superposition principle for electric fields implies that the presence of other charges does not affect the field of a charge. And although Quantum Electrodynamics (the more accurate EM theory) does not involve such things as forces and fields it does explain why that may be so. Photon, the mediator of EM force in QED, does not couple with itself.

WebTo summarize, photons ARE particles that just show wave behaviour due to us having to describe them as wave functions due to uncertainty of their position.
