The aharonov–bohm effect
WebThe Aharonov-Bohm e ect is a quantum mechanical e ect, that is, has no classical counterpart. The e ect was predicted in 1959 in a seminal paper of Y. Aharonov and D. Bohm [AB59] in which they demonstrated that a beam of electrons is a ected by the existence of the electric/magnetic eld even though electrons travel through eld-free regions. WebJan 15, 2024 · The Aharonov-Bohm effect is a celebrated quantum mechanical effect which some have claimed is an example of non-locality, i.e., of action at a distance. This thesis examines the theory and experimental tests of the effect, and compares it to another supposed example of non-locality, ...

We use a covariant formalism that is capable of describing the electric and magnetic versions of the Aharonov-Bohm effect, as well as the Aharonov-Casher effect, through local interactions of charges and currents with the quantum …
WebMay 6, 2024 · The Aharonov-Bohm experiment is basically a double-slit experiment with an added solenoid. The magnetic field B is contained entirely inside the solenoid. In addition, the solenoid is shielded to keep the electrons out. Therefore, the electrons cannot “feel” B at all. Yet it makes a difference whether the B field is on or not.
