Thanks Achuz for noticing my mistake

And that is arisen from the fact that there is no magnetic dipole, i.e., the magnetic field is divergenceless. You can derive the continuity of the normal component of the magnetic field on the boundary by imaging a small pillbox on the boundary. Maybe Griffiths already described in Chap 5.

you can express full hamiltonian by using gauge-covariant this is described in problem 9.1 of peskin and shroeder's book.

now i solved it. i was silly. thanks

and the answer will be of the form ## \partial_\mu F^{\mu\nu} = ej^\nu ## the right hand side is called Dirac current which correspond to the source term of Maxwell's equation

Thanks a lot Resnick! I'll think more. Is there any text or website you recommend? I think I have to consider birefringence but not sure how to do that

Hi, I am currently making an effort to solve a boundary value problem of electromagnetic field. The problem is as follows: The region ##y<0## is vacuum. The region ##y \geq 0## is filled with material with ##\mu=\mu_0## and dielectric tensor ## \left( \begin{array}{ccc} \alpha & i\beta &...
