Note that the operator H is selfadjoint such that it has real eigenenergies and E(m,Aθ ) = E(1 − m,−Aθ ) [the latter holds because the change m → (1 − m) and Aθ → (−Aθ ) does not change the system Eq.

Once we realize that the vector A and the vector J are in fact one and the same thing, it becomes clear that the two curl equations, (B) and (C), are jointly pointing us to an aethereal sea in which closed solenoidal circuits of magnetic lines of force are interlocked with closed solenoidal circuits ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
