In QFT, how does charge arise?

Question

I’ve read that it arises as the conserved value of a U(1) rotation, and that it in turn is a phase change, but I’m a bit lost, maybe you could explain the concept a bit more understandable?

Answer 1

A non-ELI5 question (maybe an ELI grad student) if I’ve ever seen one. Would be interesting to see if you get any good responses. Did you consider asking r/physics or r/science ?
