Physics:Quantum gauge field
From HandWiki Test
A quantum gauge field is a field associated with a local symmetry. Gauge fields mediate interactions between charged matter fields and form the basis of electromagnetism, the weak interaction, and the strong interaction in the Standard Model.[1][2]
Core idea
The field viewpoint replaces isolated particle pictures with states, modes, operators, and excitations. It is especially powerful when particle number can change.[3]
Use in quantum physics
Field concepts organize interactions, conservation laws, measurement outcomes, and effective descriptions across particle physics, optics, condensed matter, and cosmology.[4]
