Professional Experience

We have studied the dynamic mechanism of Aharonov-Bohm (A-B) effect in quantum mechanics:

We pointed out that the electric A-B effect will not exist, because the inducted charge on the inner surface of the metal tube .

We pointed out that the current explanation on the magnetic A-B effect is wrong.   It is proved theoretically that the vector potential itself cannot affect the phase of the moving charge, otherwise, the conclusion will be contradictary with the uncertainty principle of quantum mechanics. It is pointed out that the real reason of magnetic A-B effect is the interaction energy between the magnetic field produced by moving charge and the external magnetic field. 

We proposed an experimental scheme to verify the above conclusions
