Abstract

We study the system size dependence of the averaged critical conductance g(L) at the Anderson transition. We have (i) related the correction δg(L)=g()g(L)Ly to the spectral correlations, (ii) expressed δg(L) in terms of the quantum return probability, and (iii) argued that y equals η, the critical exponent of eigenfunction correlations. Experimental implications are discussed.
