Transient Response of Aharonov-Bohm Effect

Kazuhito Furuya

The transient phenomenon of the Aharonov-Bohm effect is formulated using a quantum mechanical model. As a result, it is found that the intrinsic response time is equal to the electron transit time of the ring. To apply the Aharonov-Bohm effect to high-speed devices, it is important to reduce the transit time.

The gauge invariant nonlocal quantum dynamics that is responsible for the Aharonov–Bohm (AB) effect is described. It is shown that it may be verified experimentally.

We show that the pure Aharonov-Bohm (AB) effect, or its dual (DAB), depends only on the net electric, or magnetic charge of an interfering object, however many internal degrees of freedom that system may have. The reciprocal Aharonov-Casher (AC) and He-McKellar-Wilkens (HMW) effects, on the other hand, involve physical properties---the magnetic and electric polarization of the system---which couple a system's internal degrees of freedom to its center-of-mass coordinate through the field. For composite systems this illustrates a fundamental difference between the two types of phenomenon, and one which could be important as the number of internal degrees of freedom become large. We show that, for a single internal degree of freedom, the result of this coupling is a transient loss of coherence in the observed interference of the center-of-mass coordinate.
