A Mathematically Controlled Alternative to the Supersymmetric Sigma Model of Disorder
Vincent E. Sacksteder
This paper shows how to obtain non-rigorous mathematical control over models of loosely coupled disordered grains; it provides new information about saddle point structure and pert…

The Mechanism of Localization in Weakly Coupled Disordered Grains
Vincent E. Sacksteder
It is shown that the Wegner model of disorder contains a system of constraints which is important whenever the disorder is not weak and which is responsible for localization in D >…
