Classical electromagnetism with matter particles and …
Jul 29, 2024 · Is there a way to treat classical electromagnetism in which particles are treated using Lagrangian mechanics and the electromagnetic field is treated using Lagrangian field …
Is the magnetic vector potential "real" in classical …
Aug 6, 2023 · The vector potential is gauge-dependent and unobservable in both classical and quantum mechanics. Only gauge-invariant quantities — including the electric and magnetic …
Why is $U (1)$ the gauge group in classical electromagnetism?
May 27, 2016 · Electromagnetism has to be Abelian because the light doesn't interact with itself (linearity, which implies the absence of higher-order interactions from F mu nu F mu nu), and it …
Why is classical electromagnetism linear? - Physics Stack Exchange
Oct 14, 2017 · Electromagnetism is a gauge theory with the gauge group U (1), which is abelian. This means there are no terms in the EM Lagrangian where the electromagnetic field interacts …
