Abstract
Classical and quantum electron transport in an annulus formed by a two-dimensional electron gas in a perpendicular magnetic field is studied. The transport is driven by an enclosed time-dependent magnetic flux, and is described with a Landauer-Büttiker-type formalism Transport current is generated because the transmission and reflection probabilities of the electrons which are emitted by the reservoirs on the inside and outside of the annulus are modified from their static values. The role of the probes, as well as the effect of scattering between the inside and outside of the annulus, is studued.Keywords
