Nonlocally-correlated disorder and delocalization in one dimension II: Localization length
arXiv:cond-mat/9903441 · doi:10.1016/S0550-3213(99)00313-2
Abstract
In the previous paper (cond-mat/9809323), we calculated the density of staes in the random-mass Dirac fermion system. In this paper, we obtain the mean localization length of the single-fermion Greem's function by using the supersymmetric methods. It is shown that the localization length is a increasing function of the correation length of the disorders. This result is in agreement with the density of states and the numerical studies (cond-mat/9903389).
