“…Most of the relevant properties of the quantum effects of fluxes can be discussed in terms of the two-slit interference experiment with electrons. Evidence for the AB effect have been found by Lischke [4] and Tonomura et al [5] in such experiments.…”

Dynamic behaviour of Aharonov-Bohm-type electron interference in the presence of a nonclassical electromagnetic field is investigated. The visibility of the time-averaged interference pattern is discussed for SU(1,1) coherent state (CS) and a comparison with other states is made. It is shown that the dynamic behaviour of the electron interference exhibits collapse and revival (CR) phenomenon for SU(1,1) CS. It is also shown that CR phenomenon of electron interference is closely related to the fluctuation of a nonclassical electromagnetic field.

“…These shielding electrons could in principle bring an additional phase contribution to the conventional AB phase shift of the incident electrons. Experiments carried out by Lischke, [2] Möllenstedt et al [3] and Tonomura et al [4] have demonstrated however the persistence of the conventional AB shift in the presence of metallic shields.…”

This work studies the interference of electrons in the presence of a line of magnetic flux surrounded by a normal-conducting mesoscopic cylinder at low temperature. It is found that, while there is a supplementary phase contribution from each electron of the mesoscopic cylinder, the sum of these individual supplementary phases is equal to zero, so that the presence of a normal-conducting mesoscopic ring at low temperature does not change the Aharonov-Bohm interference pattern of the incident electron. It is shown that it is not possible to ascertain by experimental observation that the shielding electrons have responded to the field of an incident electron, and at the same time to preserve the interference pattern of the incident electron. It is also shown that the measuring of the transient magnetic field in the region between the two paths of an electron interference experiment with an accuracy at least equal to the magnetic field of the incident electron generates a phase uncertainty which destroys the interference pattern.

“…Several experimental observations 1 ),2) reveal that there exists some discrepancy between the total trapped magnetic flux f/)!n existing in a multiply connected superconductor and total flux f/)ex observed outside the superconductor. Lischke 1 ) measured the temperature dependence of the total flux trapped in a superconductor cylinder with use of Aharanov-Bohm effect,3) The superconductor cylinder is with inside radius p and thickness d as seen in the insert of Fig_ 1.…”

“…The observed temperature dependence of f/)ex is shown in Fig_ 1 by solid line. When p'2>d and J..>d, a calculation 4 ) shows that the total trapped flux f/)in existing in the cylinder is , , , (1) where J.. is the penetration depth of the superconductor, f/)o=h/2e is the flux quantum, and C' is taken inside the superconductor. With the increase of temperature T to the transition temperature Te, the penetration depth J.. increases monotonically and diverges at T = Te.…”
