A Brownian motion model is devised on the manifold of S-matrices, and appliedto the calculation of conductance-conductance correlations and of the weaklocalization peak. The model predicts that (i) the correlation function in $B$has the same shape and width as the weak localization peak; (ii) the functionsbehave as $\propto 1-{\cal O}(B^2)$, thus excluding a linear line shape; and(iii) their width increases as the square root of the number of channels in theleads. Some of these predictions agree with experiment and with othercalculations only in the limit of small $B$ and a large number of channels.Comment: 5 pages revtex (twocolumn
