The credibility of digital identity information on the social web: a user study
A theory of the dynamical conductance of mesoscopic conductors is presented.
It is applied to mesoscopic capacitors, resonant double barriers, ballistic
wires, metallic diffusive wires, and to the Corbino disk and the Hall bar in
quantizing magnetic fields. Central to this approach is a discussion of the
charge and potential distribution in mesoscopic conductors. It is necessary to
take into account the implications of the long-range Coulomb interaction in
order to obtain a charge and current conserving theory. We emphasize the
low-frequency response. This has the advantage that the approach is of
considerable generality. The theory can be used to discuss the self-consistency
of the dc-conductance formula. The theory can also be applied to discuss the
rectifying (nonlinear) behavior of mesoscopic conductors.Comment: 29 pages, figures not included (preprints with figures can be
