Title: Localization of electronic states in finite ladder models: Participation ratio and localization length as measures of the wave-function extension
Author: Carrillo-Nunez, H
Schulz, PA
Abstract: In this work we discuss and compare different definitions for localization of electronic states in low-dimensional systems. We choose a heuristic model for DNA-like molecules as a system prototype in order to establish ranges of equivalence for the localization length obtained from both the conductance and participation ratios. The results suggest also criteria to infer the extension of wave function in mesoscopic systems within the diffusive transport regime as complementary information to the localization length.
