Query: Semiclassical Analysis of the Conductance of Mesoscopic Systems   The Kubo formula for the conductance of classically chaotic systems is
analyzed semiclassically, yielding simple expressions for the mean and the
variance of the quantum interference terms. In contrast to earlier work, here
times longer than $O( \log \hbar^{-1} )$ give the dominant contributions, i.e.
the limit $\hbar \rightarrow 0$ is not implied. For example, the result for the
weak localization correction to the dimensionless conductance of a chain of $k$
classically ergodic scatterers connected in series is $-{1 \over 3} [ 1 -
(k+1)^{-2} ]$, interpolating between the ergodic ($k = 1$) and the diffusive
($k \rightarrow \infty$) limits.
