Existence of a Phase with Finite Localization Length in the Double Scaling Limit of N-Orbital Models
Vincent E. Sacksteder
Among the models of disordered conduction and localization, models with orbitals per site are attractive both for their mathematical tractability and for their physical realiza…
Indications for Topological Physics in High- Materials
Vincent E. Sacksteder
Research on high- superconductors has generally not focused on analysis of the topological structure of electronic bands in these materials. In this article we collate and dis…
Electronic Conduction in Disordered Materials: Wave-like or Particle-like?
Vincent E. Sacksteder
When materials are in the diffusive regime, i.e. when the scattering length is less than the sample size, charge transport is mediated by diffusons and cooperons. We argue that the…
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 >…
Sums over geometries and improvements on the mean field approximation
Vincent E. Sacksteder
The saddle points of a Lagrangian due to Efetov are analyzed. This Lagrangian was originally proposed as a tool for calculating systematic corrections to the Bethe approximation, a…
