The AharonovâBohm effect, sometimes called the EhrenbergâSidayâAharonovâBohm effect, is a quantum mechanical phenomenon in which an electrically charged particle is affected by an electromagnetic potential (Ď, A), despite being confined to a region in which both the magnetic field B and electric field E are zero. The underlying mechanism is the coupling of the electromagnetic potential with the complex phase of a charged particle's wave function, and the AharonovâBohm effect is accordingly illustrated by interference experiments.
