Observation of the magnetic vector potential àla Aharonov-Bohm along one dimension in a magnetic field in the correspondence limit

Abstract

We report here the observation of the curl-free vector potential a la' Aharonov-Bohm in the classical macro-domain for one-dimensional motion of a charged particle in a magnetic field. The nature of this observation is emphasized here as being a hitherto unfamiliar quantum manifestation of the behaviour of the transition amplitude in the correspondence limit of large Landau quantum numbers.
