Localization and spectral statistics in a banded random matrix ensemble

M Wilkinson, M Feingold and D M Leitner

Show affiliations


The authors investigate the localization properties of the eigenvectors of a banded random matrix ensemble, in which the diagonal matrix elements increase along the diagonal. They relate the results to a transition in the spectral statistics which is observed as a parameter is varied, and discuss the relevance of this model to the quantum mechanics of chaotic Hamiltonian systems.
