I have a question connected with the problem:(adsbygoogle = window.adsbygoogle || []).push({});

https://www.physicsforums.com/threads/continuity-equation-in-an-electromagnetic-field.673312/

Why don’t we assume H=H*? Isn’t hamiltonian in magnetic field a self-adjoint operator? Why? Why do we use (+iħ∇-e/c A)^{2}instead of (-iħ∇-e/c A)^{2}two times?
